Abstract

Purpose: This study intends to develop a nonlinear cyclic plasticity damage model in the framework of finite element formulation, which is capable of taking large deformation effects into account, in order to accurately predict the hysteretic behavior of stainless steel structures. Method: The new cyclic constitutive equations that utilize the combined isotropic-kinematic hardening rule for plastic deformation is incorporated into the damage mechanic model in conjunction with the large strain formulation. The damage growth law is based on the experimental observations that the evolution of microvoids yields nonlinear damage accumulation with plastic deformation. The damage model parameters and the procedure for their identification are presented. Results and Conclusion: The proposed nonlinear damage model has been verified by simulating uniaxial strain-controlled monotonic and cyclic loading tests, and successfully applied to a thin-walled stainless steel pipe subjected to constant and alternating strain-controlled cyclic loadings.

연구목적: 본 연구에서는 대변형 효과를 구현할 수 있는 유한요소 해석기법을 기반으로 반복하중에 의한 스테인리스강의 이력거동을 정확하게 평가할 수 있는 비선형 반복소성 손상모델을 개발하였다. 연구방법: 개선된 운동경화 모델과 등방경화 법칙을 연계하여 반복하중 하에서의 재료의 거동을 모사하는데 필요한 반복소성 모델을 개발하였으며, 이를 비선형 손상모델과 결합하였다. 연구결과 및 결론: 제안된 비선형 손상모델을 검증하기 위하여 변형률 제어 단조 및 반복하중 시험을 모사하였으며, 이를 통한 해석결과를 시험결과와 비교하였다. 비교 결과, 본 연구에서 제안한 비선형 손상모델은 스테인리스강의 반복하중 하에서의 이력거동을 정확하게 모사할 수 있음을 확인하였다.
