LOCALIZATION BAND OF POST BIFURCATION IN PLANE SHEET

In order to simulate the subsequent effect caused by the flaw which is initiated at shear band bifurcation, a large strain finite element analysis is employed with an empty element technique designed to automatically release the residual stresses in the damaged elements. The damage relaxation can have either isotropic or anisotropic property. It is demonstrated that inclined localization band does radiate from the flaw in plane sheet loaded uniaxially. Thickness necking and plane shearing can be obvious...
