Patent ID: 8126658

Claim:
A non-transitory computer-readable storage medium storing a shape defect factor identification program for causing a computer to execute a process of: acquiring a deformation amount based on an elastic recovery of a certain evaluation point of before and after the elastic recovery in a case where stress distribution that acts on a work before elastic recovery is applied to the work before elastic recovery, and acquiring a region-stress application deformation amount based on the elastic recovery of the evaluation point of before and after the elastic recovery in a case where the work shape is divided into a plurality of regions set in advance, and the stress distribution is applied to the work shape before elastic recovery for every region; and comparing the deformation amount with the region-stress application deformation amount for identification of a region having the smallest difference thereof as a main influence region that is a stress distribution region most related to a shape defect of the evaluation point before and after the elastic recovery.
