In this work, geometrically nonlinear static bending analysis of sandwich beams with a porous core and two skins made functionally graded materials using mesh-free method is presented. The material types the face sheets beam are chosen so that continuity between layers guaranteed. governing equation including geometric nonlinearity established via principle virtual work. This discretized into s...

Euler, Timoshenko and high shear deformation theories to analyze the free vibration of functionally graded (FG) beam were developed. The mechanical properties this assumed differ in thickness direction according model a power-law distribution. principle Hamilton was used find equations motion. For vibration, analytical solution these presented using Navier method. effect power index, aspect rat...

Perforated discs have many applications in different parts of industry. By making such disks of functionally graded materials, more capabilities can be obtained from them. Vibration analysis of these kinds of disks can help us make them more efficient. In this paper, modeling and evaluation of disk vibration of functionally graded materials with regard to thickness were carried out using Abaqus...
