Necking of an Elastoplastic Metal Bar

Application ID: 12607

A circular metal bar of elasto-plastic material with nonlinear isotropic hardening behavior is subjected to uniaxial tension. Affected by significant stresses the bar experiences high plasticity. The phenomenon of necking is captured and its growth is accurately simulated. The change in radius is in good agreement with results found other literature. This example is a classical benchmark for large strain plasticity codes.

This model example illustrates applications of this type that would nominally be built using the following products:
