Free vibration study of sandwich plates using a family of novel shear deformable dynamic stiffness elements: limitations and comparison with the finite element solutions
(Elsevier Ltd, 2016)
In this paper, the dynamic stiffness matrix of a completely free rectangular multi-layer plate element based on Reddy's higher-order shear deformation theory is derived. The reduction of the proposed model to the first-order ...
Free vibration analysis of stiffened and cracked laminated composite plate assemblies using shear-deformable dynamic stiffness elements
(Elsevier Ltd, 2017)
In the paper, the dynamic stiffness method based on the HSDT and FSDT plate theories is applied to study free vibration characteristics of composite stiffened and cracked plate assemblies. The dynamic stiffness matrices ...
Shear deformable dynamic stiffness elements for a free vibration analysis of composite plate assemblies - Part II: Numerical examples
(Elsevier Ltd, 2017)
The dynamic stiffness elements based on the HSDT and FSDT (and the corresponding dynamic stiffness matrices of a laminated composite plate) have been implemented into the original MATLAB code, and a variety of numerical ...
Generalized plasticity model for inelastic RCFT column response
(Elsevier Ltd, 2016)
This paper presents a nonlinear 3d concentrated plasticity beam column element for the analysis of RCFT columns. The element consists of a linear elastic component with a plastic hinge at each end whose inelastic response ...
Section Discretization of Fiber Beam-Column Elements for Cyclic Inelastic Response
(Journal of Structural Engineering-Asce, 2012)
The paper presents studies of the effect of the number of material integration points at the monitored sections of fiber beam-column elements on the local response of typical structural cross sections under an extensive ...
In-plane free vibration and response analysis of isotropic rectangular plates using the dynamic stiffness method
(Elsevier Ltd, 2015)
The development of the dynamic stiffness matrix for isotropic rectangular plate with arbitrary boundary conditions undergoing in-plane free vibration is presented in this paper. Gorman's superposition method is exploited ...
An improved analysis of free torsional vibration of axially loaded thin-walled beams with point-symmetric open cross-section
(Elsevier Inc., 2016)
The objective of the paper is to analyze the influence of bimoment induced by constant axial loads on the free motion of thin-walled beams with point-symmetric open cross-section. For various boundary conditions, a closed-form ...
Research of long-term behaviour of non-prestressed precast concrete beams made continuous
(Elsevier BV, 2014)
Despite the extensive analytical and numerical research carried out in the last two decades on the long-term behaviour of continuous concrete beams composed of precast units, only limited number of experimental data is ...
On anisotropic elasticity damage mechanics
(International Journal of Damage Mechanics, 2013)
The anisotropic elasticity damage mechanics is considered within the framework of the classical theory of elasticity. Starting from the principle of strain equivalence and notion of isotropic group, damage tensor components ...
Layerwise solution of free vibrations and buckling of laminated composite and sandwich plates with embedded delaminations
(Elsevier Ltd, 2014)
Layerwise plate theory of Reddy, extended for the analysis of delaminations, has served as a basis for development of enriched finite elements. The proposed model assumes layerwise linear variation of in-plane displacements ...
