Evaluating plastic strain energy density in Mechanical using the command tool

[simeon.faller]

Hey guys,
I currently use the command tool in the Workbench for the first time because there's no output for plastic strain energy density available. The user defined result ENERGYPOTENTIAL/VOLUME evaluates the total strain energy density, containing both elastic and plastic components. The APDL command PRNSOL, SEND, PLASTIC fails with the message "The requested SEND data is not available", same for PRESOL, SEND, PLASTIC. Using other commands like ETABLE also doesn't work. But plastic strain exists so plastic strain energy density should also exist. Could anyone please explain how I can obtain the plastic strain energy density values? This would be really helpful for my Master's thesis!
FYI: I use TET10-Elements and a static structural analysis (tensile test).

Hi Simeon,

To obtain plastic strain energy density or "plastic work" in Ansys Mechanical, set the Nonlinear Data to Yes under Analysis Settings before running the analysis.

Next, after the solution is complete, highlight the Solution branch and insert the variable NLPLWK accessible from the Worksheet.
