functionally gradedpoisson’s ratio structures have been developed for critical protection. in thispaper, the static bending and buckling of fgpr nanoscale beam are studied basedon the nonlocal timoshenko beam model, in which both young’s modulus andpoisson’s ratio are assumed to vary continuously in the thickness direction. byutilizing total potential energy principle, equilibrium equations are...

Generation of Bessel-like beam array from polymeric microstructures, which were created using four-beam interference lithography is demonstrated. Quality of the produced Bessel-like beams depends on the geometrical parameters of the manufactured axicon-like structures, and their shape can be efficiently controlled through the laser treatment parameters. The output beam characteristics indicate ...

Automotive design engineers face the challenging problem of developing products in highly competitive markets. In this regard, using conceptual models in the first step of automotive development seems so necessary. In this paper, to make a body in white conceptual model, an engineering approach is developed for the replacement of beam-like structures, joints, and panels in a vehicle model. The ...

In this contribution, a previously introduced discrete model for studying the statics of duoskelion beam-like structures is extended to dynamics. The results numerical simulations performed using such an are reported discuss in-plane dynamic buckling under different loading and kinematic boundary conditions. core instrument analysis beam element, which, in addition flexure, also accounts extens...

Cracks and other damages generated during the service of bridges can reduce load bearing capacity threaten operational safety.Finite Element Model Updating (FEMU), as one important means structural health diagnosis, identifies damage through changes in model parameters. The three key factors FEMU are updating variables, objective functions, optimization algorithms. poor selection above existing...
