Free Vibration Analysis of Porous Functionally Graded Material Sandwich Folded Plates
摘要
The current work deals with the fundamental frequencies of porous FGM sandwich folded plates using the finite element analysis. The FEM formulation is based on First-order shear deformation theory (FSDT). The lower and the upper layers of the plate made of FGM are composed of pure metal and pure ceramic and the FGM is used for core. The present formulation is modeled using an 8-noded element along with five degrees of freedom. The output of the current analysis matches well with the benchmark methods.
