The methodology for calculating the energy and deformation parameters of the processes of free extrusion of glasses with a counter-punch is described. Extrusion of both non-hardening and hardening material is considered. In the latter case, accounting for the hardening of the extruded material is described in detail. The above formulas allow us to determine such important parameters of the stamping process as the total and specific deforming forces, maximum pressure on the matrix wall, and increase in yield stress.
