Forming simulation method, forming simulation apparatus, forming simulation program, and recording medium
摘要:
The present invention provides a press forming simulation method using a finite element method for a sheet metal, in which a deformation state of a pressing tool is represented with high accuracy by superimposing at least one natural mode, for the surface shape of the pressing tool, in a no-load state.
