How are the residual stresses measured?

Here is how I simulate residual stress:

  1. Create a material that uses one of the Plasticity material models such as Bilinear Kinematic Hardening.
  2. Create support boundary conditions.
  3. Apply sufficient load to the intital geometry to cause the material to exceed the yield strength.
  4. Remove the load.
  5. Plot the residual stress.
  6. Plot the residual deformation.
