<p><P>PROBLEM TO BE SOLVED: To efficiently identify an elasticity matrix of a macro model when performing multi-scale simulation on a tire or structure having a composite material. <P>SOLUTION: A relationship between stress and distortion or a relationship between power and displacement in a plurality of deformation modes is acquired from a result of deformation analysis, and a first elasticity matrix under maximum rigidity of a macro structure model and a second elasticity matrix under minimum rigidity are determined from the relationship between stress and distortion or the relationship between power and displacement. The first elasticity matrix and the second elasticity matrix are then used to set an initial value and a search range for identifying an elasticity matrix of the macro structure model, and the elasticity matrix of the macro structure model is identified in such a manner that a relationship between stress and distortion in deforming the macro structure model is matched with the relationship between stress and distortion. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
