FRACTURE PREDICTION METHOD, PROCESSING DEVICE, PROGRAM PRODUCT AND RECORDING MEDIUM

摘要

When performing an analysis by dividing an analysis object into a plurali ty of elements, adjacent two elements are combined after the analysis or the analysis is performed by using two sizes of the divided elements so as to c ompare the plate thickness reduction ratio or the maximum main distortion at the same position including the same element. The element which exhibits a large difference as a result of the comparison is extracted as a breakage da nger region. With this configuration, it is possible to surely extract a bre akage danger portion when predicting a breakage by the finite element method .
