PROBLEM TO BE SOLVED: To highly accurately analyze an actual destructive behavior and a load-displacement diagram by representing fragments of a destroyed molded article on computer simulation.;SOLUTION: A calculation model creation section 11 creates a finite element model representing the shape of a molded article to be analyzed by pluralities fo nodes and elements, a finite element analysis section 12 executes finite element analysis using the finite element model, determines whether there is any element satisfying a destruction condition based on the result of the finite element analysis, and deletes, when it is determined that there is an element satisfying the destruction condition, the element from the finite element model, an element restoration section 13 restores the element as the target of finite element analysis in the separated state of the element from the finite element model after a predetermined period of time from the deletion of the element, and generates a new node accompanying the restored element, and the finite element analysis section 12 executes finite element analysis in view of contact between the element restored by the element restoration section 13 and the finite element model.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2016,JPO&INPIT
