Abstract
A forming simulation method of an elastic-plastic material, which includes: calculating an element equivalent nodal force vector from stress tensor using a finite element method for one or a plurality of finite elements of a target configuration of the elastic-plastic material; and calculating the total equivalent nodal force vector of areas by integrating the element equivalent nodal force vector for the calculated one or more finite elements over all the areas or specified areas of the elastic-plastic material.
