Abstract

In the present study, the collapse behavior of a thin-plate subjected to axial compression is investigated parametrically using the finite element method. It is revealed that the axial collapse of the plate, which has various hardening characteristics, is induced by two dominant factors: the stress limitation of the material and the limitation of in-plane deformation at the side edges of the plate. Then, a simplified collapse condition, which corresponds to two modes, is derived based on the plastic buckling theory and the effective width concept, and the validity of the simplified collapse condition is then verified by the comparison of numerical results obtained using various material and geometric properties.
