    첫댓글 You may get the same stress value even though you repeat thousands of loading steps (unless you account for damage accumulation). Fatigue prediction is basically empirical which means that the approach is very different from conventional mechanics approaches. You may want to review some fatigue texts prior to solving the rail problem. I also have some concerns about the contact properties. Hope this would help.

    Thanks for your solutions. After reading your responding, I am wondering how to apply for damage accumulation? Would you give me a any tip?
