The most dangerous fracture of creep-fatigue is caused by multiple small cracks which initiate and grow inside of materials. In this study, a numerical simulation method is proposed on the initiation and growth of inner small cracks on the basis of the experimental observation of a Type 304 stainless steel during creep-fatigue in order to elucidate the evolution process of damage. The model proposed in this study is similar to that for creep-fatigue intergranular fracture of surface cracking type which has already been reported by the authors. It is based on a discrete model of grain boundaries having random shape and sizes with random fracture resistances and a Monte Carlo simulation combined with a damage mechanics concept. As a result, the spatial and temporal distributions of inner small cracks are successfully evaluated by the simulation.
