composite fatigue

    • rakesh9736

      Is it possible to do fatigue analysis of composites in Ansys Fatigue module without Ansys nCode?

      If one characterized the fatigue strength with representative S/N curve empirically from test in specific failure modes say tension or bearing etc. yes it can. You relate the far field or nominal stress to the failure. But if it is looking for more micro-mechanics Then no. And nCode just does short fiber. The fatigue of composites is quite complex with many newer techniques coming out of academia.
