Towards an optimisation of forging processes using geometric parameters

Nowadays computer simulation is used in metal forming to reduce the use of experimental investigation and tests required in a real tryout process. For much of the time, specialists have some freedom to obtain the desired forged parts, which is why numerical simulations are applied in most engineering offices and manufacturing industries to evaluate the forming difficulties in metal forming processes. In the mechanical system and concurrent engineering laboratory (LASMIS), a finite element package has been developed to solve elasto-plasticity problems with ductile damage in large deformation. In this article an experimental design is presented in order to show the influence of geometric parameters of a turbine engine disk on the total strain energy and the average of the elasto-plastic strain.
