In this paper, the effects of three types porosity on bending behavior functionally graded porous (FGP) beams are studied. The finite element procedure is established and based simple Timoshenko beam theory. results achieved in paper presented compared with other references to verify feasibility implementing formula writing Matlab code. On hand, can help researchers have an overview beams.

Free bending vibration analysis of the functionally graded viscoelastic circular sandwich plates is accomplished in the present paper, for the first time. Furthermore, local shear corrections factors are presented that may consider simultaneous effects of the gradual variations of the material properties and the viscoelastic behaviors of the materials, for the first time. Moreover, in contrast ...
