ABSTRACT:
The analysis model generation unit generates an analysis model for use in an analysis by a finite-element method. A stress distortion analysis unit analyzes a stress and a distortion occurring in finite elements of a continuum by a load using the analysis model for each load cycle cyclically applied to the continuum by the finite-element method. An element damage evaluation unit evaluates a damage by the distortion on the finite elements of the continuum based on the analysis result for each load cycle. A crack growth display unit displays the growth of a crack occurring in the continuum based on a result of the evaluation of the damage.
