Abstract

Abstract

The dynamic response of simply supporting rigid-plastic circular plate is analyzed using the plastic limit method along with Taylor plate theory. Parameters including maximum residual deformation field are obtained and compared with the FEM results. It is shown that the method is feasible for small deformation and short duration of loading. The influence of fluid-structure interaction and cavatation is also discussed.
