摘要
There is provided an analysis method whereby, when a proposed plan for deforming a resin molded article (for example, a countermeasure plan for warpage) is created and designed, it is possible to create a more effective proposed plan in a short time and in which computation cost is considerably reduced. In an deformation state analysis method of analyzing, for a resin molded article to be deformed, a deformation state of the resin molded article by optimizing an objective function under a prescribed restraint condition and a prescribed limiting condition, using a topology optimization method dividing the resin molded article into micro regions, the prescribed restraint condition is a trend of the amount of deformation of the resin molded article, the prescribed limiting condition is a contribution rate expressing an extent to which deformation of each micro region contributes to deformation of the resin molded article, and in the optimization of the objective function optimization is performed so as to minimize rigidity of the resin molded article.
