Abstract:This work presents an analysis of the plate drawing processes carried out in converging dies. The analysis has been made by the upper bound method (UBM), modeling the plastic deformation zone by triangular rigid zones (TRZ), and considering that the processes occur under plane strain and partial friction conditions. The goal is to evaluate how the work-hardening suffered by materials when they are cold-worked affects the energy required to carry out a certain process. In order to achieve this objective, the pa… Show more
