von Mises stress exceeds the yield point, but plastic strain is zero

      Hello sir,

      I'm doing a static analysis of metal parts, where the yield point of the material changes with temperature, the yield point of the material at a temperature of 800 degree is about 80Mpa. The result is that the MAX von Mises stress of node is 140Mpa and the node temperature is around 800 degree, which exceeds the yield point of the material, but the plastic strain is 0. May I ask the reason for it.

      Would you like to give me suggestions? Thank you in advance.

      Hello dear Seki.
      Do you define plastic properties in the material library (engineering data)?

      Hello dear HesamK,
      Thanks a lot.
      There is input miss about engineering data.
      The problem is fixed.
