<P>PROBLEM TO BE SOLVED: To predict and evaluate a shape failure due to surface distortion in a press molded article. <P>SOLUTION: After analyzing a molding process of a target area in a press molded article, the target area is divided into a plurality of areas, and elastic recovery of one area is analyzed. Next, analyzing an elastic recovery amount about an area expanded meeting with an adjacent area is sequentially repeated, an elastic recovery state of the entire target area is finally calculated, an inclination change in surface is evaluated by performing secondary differentiation of the obtained surface shape in a certain direction, and the occurrence position and occurrence degree of surface distortion in the molded article are predicted and evaluated on the basis of a distribution of the evaluation values. <P>COPYRIGHT: (C)2008,JPO&INPIT |
