✦ Synopsis
Finite element analyses of backward can extrusion are performed with two punch dimensions to enhance the sliding or the sticking of workpiece material at the punch nose contact surface. The punch geometry effect on the effective plastic strain and hydrostatic stress distributions are discussed and the evolution of microvoid volume fraction during the whole extrusion is predicted.
