Abstract

Abstract: Gradation along the plate thickness is considered in plate structures in practice. It concerns especially issues of linear and non-linear stability of functionally graded (FG) structures. In the present work, a square in-plane FG plate made of a step-variable gradation material was assumed. A five-strip FG plate with two cases of boundary conditions: simply supported on all edges and clamped on longitudinal edges was considered. A stability problem of the FG plate subjected to compression and shear load and a non-linear issue of stability of the compressed plate was solved. To compare the results, the calculations were carried out with three methods.
