Residual Stress — How Does ANSYS Calculate That?

  I am doing a Static Structural simulation in ANSYS Workbench. I am using "Multilinear Isotropic Hardening". How does ANSYS calculate the "Stress", when the strain passes the "Elastic Limit". I am curious to know the Math behind the results.
  Any explanations, please? Thanks.

  Hi,
  The multilinear isotropic hardening behavior can be described based on a piece-wise linear stress-plastic strain curve. To know more about how it is calculated, you may refer to the Ansys Help document here - Rate-Independent Plasticity
  Hope this helps!
