Extreme deformation of edge-fixed round steel plate under the action of a spherical punch which radius is much smaller than the radius of the plate

Abstract

The paper outlines the results of application of an axisymmetric rigid-plastic momentless finite element model in investigation of the process of forming round steel plate by a spherical punch which radius is significantly smaller than the radius of the plate. The breaking of molded shell is predicted by computational model by strain localization. Numerical simulation results were compared with experimental data.
