Claim One:
1. A crack growth evaluation apparatus that evaluates growth of a crack occurring in a continuum, comprising: a model generation unit generating an analysis model used in analyzing a stress and a distortion occurring in the continuum by a finite-element method and obtained by dividing the continuum into a plurality of finite elements; an analysis unit analyzing by the finite-element method a stress and a distortion occurring by a load cyclically applied to the continuum in each of the plurality of finite elements of the continuum for each cycle of the load using the analysis model; an evaluation unit evaluating damage caused by the distortion occurring in the continuum for each of the plurality of finite elements of the continuum for each cycle of the load cyclically applied to the continuum using the analysis model based on a result of an analysis by the analysis unit; and a display unit displaying growth of a crack occurring in the continuum using the analysis model based on a result of an evaluation of the damage by the evaluation unit.
