STRESS CALCULATION DEVICE, STRESS CALCULATION METHOD AND PROGRAM

PROBLEM TO BE SOLVED: To provide a stress calculation device etc. capable of accurately and easily obtaining stress.SOLUTION: In the stress calculation device of the embodiment, a proportion storage part 12 stores therein a plurality of proportions of stress which are generated at evaluation points of a plurality of partial element models different in shape of a structure in accordance with an external force caused to act on boundaries of the partial element models. A boundary force calculation part 21 calculates, as boundary forces, loads generated in portions located on boundaries of the partial element models in an entire model of the structure. A coefficient calculation part 22 obtains, as a coefficient, a proportion corresponding to the structure using the plurality of proportions stored in the proportion storage part 12. An evaluation point stress calculation part 23 integrates the boundary forces obtained by the boundary force calculation part 21 and the coefficient obtained by the coefficient calculation part 22 to calculate stress generated at evaluation points of the structure.
