Free vibration analysis of functionally graded porous plate using 3-D degenerated shell element

The free vibration analysis of porous functionally graded (FG) plates using 8-noded three-dimensional degenerated shell element has been presented in this paper. The Reissner–Mindlin assumptions, which converts 3D field into an equivalent 2D field in terms of mid-surface nodal variables, are employe...
