AB  - Dynamic analysis of a spatially curved Bernoulli-Euler beam subjected to the moving load is considered in this paper. The isogeometric approach is used for the spatial discretization of the weak form of the equation of motion. Both the reference geometry and the solution space are represented using the same NURBS basis functions that guarantee an accurate description of beam’s centerline. The time integration is done by the explicit technique. The presented formulation is validated by the comparison with the existing results from the literature for the curved beam subjected to the constant load moving with the constant velocity.
AB  - У овом раду је приказана динамичка анализа просторне криволинијске Бернули-Ојлерове греде под утицајем покретног оптерећења. Изогеометријски приступ је примењен у циљу просторне дискретизације слабе форме једначина кретања греде. Овај приступ се базира на примени истих базних NURBS функцијa за описивање геометрије и кинематике криволинијске греде, чиме је омогућен тачан приказ системне линије греде. Временска интеграција једначина је извршена применом експлицитне методе. Приказана формулација је валидирана поређењем са резултатима из литературе за случај криволинијске греде оптерећене покретном силом константног интензитета и брзине.

AB  - Accurate numerical modeling of curved beams is of significant importance in different engineering fields. Several challenges can be present during the curved beam formulation, primarily due to the issues regarding the beam geometry, discretization and beam theory assumptions.
In this dissertation, the isogeometric approach is applied in the dynamic analysis of spatial curved beams. A novel beam element was formulated using the Bernoulli - Euler hypothesis and the fundamental relations of the differential geometry, as well as the Cauchy continuum beam model. The geometry of the beam, as well as the displacement, velocity and acceleration fields, were defined using the Non-Uniform Rational B-Spline (NURBS) basis functions, which present the basis concept of the isogeometric approach. Complex geometry of the curved beams can be modeled accurately using NURBS - based isogeometric approach. Formulation of the spatial beam is conducted for the linear case, while the geometrically nonlinear formulation is conducted only for the plane curved beam using an explicit integration procedure. Free and forced vibration analyses of the curved beams are studied. In the latter, the influence of the moving mass on the curved beams is analyzed. The presented approach had shown that, in comparison to the classical finite element method (FEM), a less number of degrees of freedom are required in order to obtain accurate results. Consequently, fewer computational resources are needed to reach the appropriate level of accuracy for the curved beams. This makes the presented approach competitive with the conventional FEM, especially in the analysis of the flexible spatial engineering structures with complex geometry.
AB  - Tačno numeričko modeliranje krivolinijskih grednih nosača je od izuzetnog značaja u mnogim inženjerskim oblastima. Geometrija krivolinijskog grednog nosača, diskretizacija grede kao i potrebne pretpostavke grede, predstavljaju poteškoće prilikom formulacije krivolinijskog grednog elementa.
U ovom radu je primenjen izogeometrijski pristup u dinamičkoj analizi prostornih krivolinijskih grednih nosača. Novi gredni element je definisan primenom Bernuli - Ojlerove pretpostavke, kao i osnovnih relacija diferencijalne geometrije i mehanike kontinuuma Košijeve grede. Geometrija grede, kao i polje pomeranja, brzine i ubrzanja su definisani primenom NURBS baznih funkcija, što predstavlja fundamentalnu osobinu isogeometrijskog pristupa. Složena geometrija krivolinijskog grednog nosača može se tačno modelirati primenom izogeometrijskog pristupa zasnovanog na NURBS baznim funkcijama. Formulacija prostornog krivolinijskog grednog nosača je izvedena u uslovina linearne teorije, dok je geometrijski nelinearna teorija primenjena samo na ravanskom krivolinijskom grednom nosaču, primenom eksplicitne metode integracije. Izvšena je analiza slobodnih i prinudnih vibracija. Analiza prinudnih vibracija je fokusirana na uticaj pokretnog opterećenja na krivolinijski gredni nosač. Primenom date formulacije dobijeni su rezultati zadovoljavajuće tačnosti sa manje stepeni slobode u poredjenju sa klasicnom metodom konačnih elemenata. U sladu sa tim, u cilju dobijanja rezultata zadovoljavajuće tačnosti krivolinijskog grednog nosača nepohodna je primena manje resursa. Ovo čini prikazani pristup konkurentnijim klasičnoj metodi konačnih elemenata u analizi fleksibilnih inženjerskih konstrukcija sa složenom geometrijom.

AB  - In this paper, linear transient analysis of spatial curved Bernoulli – Euler beam with circular cross – section formulated using isogeometric approach has been presented. The isogeometric approach is based on the concept that the geometry of the beam, as well as the displacement field are defined using the Non – Uniform Rational B – Spline (NURBS) functions. Governing equations of motions are derived using the basic relations of the differential geometry and continuum mechanics. In order to conduct transient analysis, time discretization has been employed using explicit integration scheme. The validation of the proposed method has been carried out for the spatial curved cantilever beam subjected to the point load with constant magnitude. The results of the free end displacements obtained using proposed method have shown excellent convergence properties and agreement with the results obtained using finite element-based software. In comparison to the conventional finite element method, less number of degrees of freedom are required in order to obtain accurate results.

AB  - In this paper dynamic analysis of a curved Bernoulli – Euler beam subjected to a moving load is presented. Moving load is modelled as a single force with constant magnitude and direction, which moves along its trajectory. Plane curved Bernoulli – Euler beam element is formulated using isogeometric approach where both the displacement field and geometry of the beam are described using NURBS basis functions. Behavior of the beam element is defined and studied in the case of linear formulation where displacements and displacement gradients are assumed to be small. Validation of the proposed approach is presented for the plane curved beam subjected to moving load with constant velocity, magnitude and direction.

AB  - In this paper the linear free vibration analysis of an arbitrarily curved spatial Bernoulli – Euler beam with circular cross section using isogeometric approach has been presented. In order to carry out free vibration analysis of the beam, the stiffness and mass matrices have been derived using basic properties of the continuum mechanics and differential geometry. The isogeometric approach is based on the idea that both the geometry and the displacement fields are described using the same basis functions - NURBS (Non – Uniform Rational B – Spline). The validation of
the proposed approach has been carried out on the spatial beam with arbitrary shape. Natural frequencies and mode shapes have shown good agreement with the results obtained using software based on classical finite element method.

The geometry of the beam as well as the displacement field are defined using the NURBS basis functions which present the basic concept of the isogeometric analysis. A novel approach based on the fundamental relations of the differential geometry and Cauchy continuum beam model is presented and applied to derive the stiffness and consistent mass matrices of the corresponding spatial curved beam element. In the Bernoulli–Euler beam element only translational and torsional inertia are taken into account, while the Rayleigh beam element takes all inertial terms into consideration. Due to their formulation, isogeometric beam elements can be used for the dynamic analysis of spatial curved beams. Several illustrative examples have been chosen in order to check the convergence and accuracy of the proposed method. The results have been compared with the available data from the literature as well as with the finite element solutions.

AB  - Isogeometric analysis (IGA) is based on a concept that uses the same base functions for representing both the model geometry and the solution space. The most common base functions used in the IGA are NURBS (Non-Uniform Rational B-Splines) functions for their capability to analytically represent various geometries. In this paper, the IGA is applied in the free vibration analysis of rotation-free plane curved Bernoulli-Euler beam. The stiffness and mass matrices have been developed using basic concepts of continuum mechanics and the principle of virtual work. Geometry of the undeformed and deformed beam is defined using convective coordinates and cross section basis vectors. Results of the free vibration analysis for beam with arbitrary curvature are compared with the results obtained from the conventional finite element method (FEM) software. The significant advantages of the IGA approach over the FEM are shown and discussed.

AB  - The free vibration analysis of stiffened plate assemblies is presented in this paper by using the dynamic stiffness method. The transformed dynamic stiffness matrix of completely free rectangular Mindlin plate is derived by using the transformation matrix. In addition, the global dynamic stiffness matrix of plate assembly is derived by using similar assembly procedure as in the finite element method. The natural frequencies of stiffened plate assemblies with arbitrary boundary conditions are computed and validated against the results obtained by using the finite element software Abaqus. High accuracy of the results is demonstrated.
AB  - U okviru ovog rada analizirane su slobodne vibracije ploča sa ukrućenjima primenom metode dinamičke krutosti. Razvijena je transformisana dinamička matrica krutosti potpuno slobodne pravougaone Mindlin-ove ploče korišćenjem matrice transformacije. Takođe, izvedena je globalna dinamička matrica krutosti sistema ploča koristeći sličan postupak kao u metodi konačnih elemenata. Određene su sopstvene frekvencije ploča sa ukrućenjima za različite konturne uslove i upoređene sa vrednostima dobijenim po metodi konačnih elemenata primenom programskog paketa Abaqus. Dobijeni su rezultati visoke tačnosti.

AB  - Isogeometric analysis (IGA) is based on a concept that uses the same base functions for description of displacement field and undeformed model geometry. The most common base functions used in the IGA are NURBS functions. In this paper, the IGA is applied in the free vibration analysis of beam element. The stiffness and mass matrices have been developed for rotation-free Bernoulli-Euler and Timoshenko beam using the Galerkin method. Natural frequencies of beam element with specific boundary conditions have been computed using the isogeometric approach. The results were compared with the exact analytical solutions obtained by using the dynamic stiffness method (DSM) and the conventional finite element method (FEM).
AB  - Изогеометријска анализа (ИГА) се базира на концепту коришћења истих функција за описивање поља померања констукције као и геометрије недеформисаног модела. Најчешће коришћене базне функције у ИГА су NURBS фунцкије. У овом раду, ИГА је коришћена у анализи слободних вибрација гредног елемента. Да би се добили потребни резултати, матрица крутости и матрица маса је изведена за Bernoulli-Euler-ову греду код које су непознате само попречна померања, као и Timoshenko-ву греду помоћу Galerkin-ове методе. Нумеричка анализа приказана је на примеру гредног елемента са конкретним граничним условима. Тачност резултата добијених помоћу ИГА је проверена поређењем са резултатима добијеним методом динамичке крутости и методом коначних елемената.

AB  - In this paper, the Dynamics Stiffness Method, which yields “exact” results for a certain class of plate structures, is applied to analyze free vibration of rectangular plates perpendicularly assembled. In order to obtain necessary results, the transformation matrices have been developed for three characteristic positions of rectangular plates. Numerical example is conducted for so-called L plate, consisting of two plates perpendicularly connected. In addition, numerical example is also conducted for so-called box, consisting of six rectangular plates perpendicularly connected. All plates have the same geometrical and mechanical properties. The accuracy of the results obtained by the Dynamics Stiffness Method is verified by comparing them with the solutions obtained by conventional Finite Element Method. The convergence of the computed natural frequencies is found to be rapid and excellent.

AB  - In this paper different mathematical models of the vehicle load are presented, depending on the one of the moving load types. In general, vehicle load models can be classified into two types: static and dynamic moving load models. Static moving load model is model with nonvarying load value and shape in time. Dynamic moving load model is defined by differential equations of motion where the road roughness function affects the solution. Due to this influence some of the differential equations cannot be solved analytically and the numerical approach has to be performed. Therefore, in this work Matlab Simulink models have been developed to solve this problem. Validation of Simulink models is carried out and presented for all analysed dynamic moving load models.

AB  - Bridge flutter phenomenon presents an important criterion of instability, which has to be considered in the bridge design phase. This paper presents different bridge flutter methods which can be used to solve the flutter problem, such as most commonly used frequency-domain approach, then equivalent approuch in time-domain, and the approximation based on the quasi-steady theory. A numerical example related to the tipical bridge cross-section follows presented approaches.
AB  - Феномен флатера мостова представља вазан критеријум стабилности, који мора бити узет у обзир током процеса пројектовања. У овом раду су приказане различите методе за решавање проблема флатера, међу којима су приступ у фреквентном домену, еквивалентни приступ у временском домену, као и апроксимација на бази квази-стационарне теорије. Нумерички пример типичног попрепчног пресека моста прати приказане приступе.

AB  - Bridge flutter phenomenon presents an important criterion of instability, which should be considered in the bridge design phase. This paper presents different bridge flutter methods which can be used to solve the flutter problem. Most commonly used frequency-domain approach is based on the formulation of aero elastic forces with frequency dependent coefficients called flutter derivatives. The critical wind speed, as the main critical condition for the onset of flutter is obtained based on these aero elastic forces. Aero elastic forces can be also expressed in the time-domain, using so-called indicial functions. These functions are usually determined from the corresponding flutter derivatives. In situations when fluid-memory effects tend to become small the quasi-steady theory can be used as an approximation of aero elastic forces. A numerical example related to the typical bridge cross-section follows presented approaches. .

U ovom radu su prikazane različite metode koje se mogu koristiti pri rešavanju problema flatera. Najčešće korišćeni pristup je u frekventnom domenu i baziran je na formulaciji aeroelastičnih sila putem frekventno zavisnih koeficijenata koji se nazivaju flater derivati. Na osnovu ovako izraženih aeroelastičnih sila, određuje se kritična brzina vetra, kao glavni uslov za nastanak flatera. Aeroelastične sile mogu se takođe izraziti i u vremenskom domenu, pomoću takozvanih indicijalnih funkcija. Ove funkcije su najčešće određene iz odgovarajućih flater derivata. U slučajevima kada su efekti memorije fluida zanemarljivi, kvaziustaljena teorija može se koristiti za aproksimaciju aeroelastičnih sila. Numerički primer tipičnog poprečnog preseka mosta prati prikazane pristupe. .

AB  - In this paper, the Spectral Element Method (SEM) is applied to analyze free vibration of two plates perpendicularly assemblied, so-called L plate. In order to obtain necessary results, the transformation matrices have been developed for two positions of rectangular plates. Numerical example is conducted for L plate assemblies consisting of rectangular plates with same mechanical and geometrical properties. The accuracy of the results obtained by the SEM is verified by comparing them with the solutions obtained by conventional Finite Element Method (FEM).
