Large deflections of rigid-plastic plates
Transversally loaded plastic plates can support loads exceeding the bending collapse pressure. This is due to the fact that the intrinsic geometry of a structure changes in the process of plastic flow. With any transient shape of the deformed structure a collapse load can be associated. The sequence of such loads yields a load-deflection relationship differing considerably from that of bending collapse. In a study of post yield behaviour of perfectly plastic plates, therefore, deflections can not be considered small in comparison with the plate thickness.
