손상도 모델에 따른 인장시험 중 파단 예측 결과의 변화

In this paper, finite element predictions of tensile test of a cylindrical specimen are conducted for different damage models. An optimized analysis model to predict tensile test with emphasis on fracture is introduced. McClintock damage model, Rice-Tracey damage model, Cockroft-Latham damage model, Freudenthal damage model, Brozzo et al. damage model and Oyane et al. damage model are used and the predictions are compared to evaluate the damage model from the viewpoint of tensile test.
