MOLDING SIMULATION METHOD, MOLDING SIMULATION DEVICE, PROGRAM, RECORDING MEDIUM, AND MOLDING METHOD BASED ON SIMULATION RESULT

WIPO Patent Application WO/2010/038539

A1

Provided is an elastic-plastic material molding simulation method including: a step of using the limited element method to calculate an element equivalent node force vector from a stress tensor for each one or each group of the limited elements in a target shape of the elastic-plastic material; and a step of integrating the element equivalent node force vector calculated for each one or each group of the limited elements in the entire or in a specific region of the elastic-plastic material so as to calculate all the equivalent node force vectors in the region.
