User Defined Function for Incremental Plastic Strain

    • DoodlerD


      For a nonlinear analysis, how can I plot the "incremental" plastic strain? Is it the difference in strain between two substeps? The standard EPPL controls dont seem to be working.

      Thank you!

      As the plastic strain increments, it is accumulated in NL,EPEQ. This is the accumulated equivalent plastic strain, which is a scalar measure and always monotonically increasing. If you take the difference between two substeps, you are getting the incremental equivalent plastic strain.
      I hope that helps.
      Regards Sean
