Low energy impact damage detection in laminar termoplastic composite materials by means of embedded optical fibers
(Materials Science Forum, 2005)
The possibility of applying optical fibers as sensors for investigation of real time low energy impact damage in laminar thermoplastic composite materials has been studied. For that purpose intensity based optical fibers ...
Should particle trajectories comply with the transverse momentum distribution?
(European Physical Journal-Special Topics, 2008)
The momentum distributions associated with both the wave function of a particle behind a grating and the corresponding Bohmian trajectories are investigated and compared. Near the grating, it is observed that the former ...
Quantum operators in Weyl quantization procedure via Wigner representation of quantum mechanics - quantum phase operator as a special case
(Wiley-VCH Verlag, 2003)
Coherent states, in Wigner representation of quantum mechanics which is classical in structure with Wigner function playing the role of classical phase space probability distribution, and standard quantum mechanical ...
Modelling behaviour of bridge pylon for test load using regression analysis with linear and non-linear process / Modeliranje ponašanja pilona mosta na probno opterećenje primjenom regresijske analize kao linearan i nelinearan proces
(Geodetski list, 2011)
This paper presents the procedure for dynamic system identification regarding behaviour of bridge pylon for test load, and the numeric example had been illustrated by examination of "Sloboda" bridge in Novi Sad. Since pylon ...
An intensity based optical fiber sensor for low velocity impact detection in unidirectional composites
(Advanced Composite Materials, 2000)
Prevention df serious damage of composite structures might be achieved by inspecting the structural integrity during exploitation. This paper decribes the design and development of a promising optical fiber sensor system ...
Fracture of reinforced concrete beams subjected to three point bending
(International Journal of Damage Mechanics, 2003)
The present paper investigates deformation of three point bent reinforced concrete (RC) beams analytically (using fracture mechanics), computationally (using finite element method) and experimentally. As the applied force ...
Indentation damage detection in thermoplastic composite laminates by using embedded optical fibers
(Soc. for the Advancement of Material and Process Engineering, 2005)
In recent years, optical fibers have received attention as sensors for the purpose of in-service health monitoring in composite materials. Advantages of optical fiber sensors over conventional sensing methods are well-known ...
Evaluation of the fourier transform of e(-ux2) for imaginary U
(Springer Science and Business Media Deutschland GmbH, 2006)
It is shown that the Fourier integral of the function exp(-ux(2)) exists not only for u satisfying Re u gt 0 but also for u that satisfies Re u >= 0. The proof is given by evaluating this integral for imaginary u.
A contribution to the analysis of box beams with deformable cross section
(Journal of Constructional Steel Research, 1988)
This paper compares the simplified theory of thin-walled box beams with deformable cross section given by Sedlacek with the more accurate approach proposed by Kollbrunner and Hajdin. Single-cell, simply supported box girders ...
Fatigue damage detection in composite rods using fiber optic intensity based sensors
(Trans Tech Publications Ltd, 2004)
An application of the embedded intensity based fiber optic sensors (FOS) for fatigue damage detection in cantilevered composite rods is presented. During the fatigue test with constant amplitude of oscillations, the ...
