Abstract
A numerical method is proposed for calculating the strain during hot o pen-die forming of porous preforms. With this model the density distri bution in various stamping zones at any stage of the process can be es timated as a function of the preform size and the geometry of the empt y die. The optimal parameters for the process can be chosen on the bas is of the results.
