Analytical solutions for nonlinear vibration of porous functionally graded sandwich plate subjected to blast loading

This paper presents the nonlinear vibration of porous functionally graded sandwich plate on elastic foundations subjected to blast loading by the analytical approach. The sandwich plate consists of two FGM face sheets and a homogeneous core which is made from metal or ceramic. Two types of porosity...
