Plastic forming processes of transverse non-homogeneous composite metallic sheets

In this work an analysis of the radial stress and velocity fields is performed according to the J2 flow theory for a rigid/perfectly plastic material. The flow field is used to simulate the forming processes of sheets. The significant achievement of this paper is the generalization of the work by Na...
