Abstract

The problems of modeling in the CAE-system of panels forming processes in the creep mode with the use of reconfigurable rod punch are considered. The geometrical and contact nonlinearity are taken into account in the model of the problem. For the formulation of rational deformation problems the damage parameter is taken as an optimization criterion. A discrete optimal control problem is formulated, which is solved by the method of dynamic programming with improvement by the method of local variations
