概要

In recent years, as is the same in other technological fields, many technologies have been developed efficiently by aggressively using computer simulations in the field of plasticity technology. We also widely utilize simulations for advanced evaluations of the deformability and for troubleshooting during prototype production. In this paper, we will introduce an example of sheet metal forming part for an automobile air-conditioner compressor. We have improved the axial-symmetric FEM (finite element method) solver to treat the Lankford value of sheet metals. Specifically, we used the Hill's yield function which is concerned with metallic unisotropy. By applying the FEM solver to the sheet metal forming processes, we designed a series of sheet metal forming processes for the compressor part.
