  Could anyone tell me where to find the Mean Ipt effective strain which I show below in LSDYNA? I can't find it in my d3plot file.
  The corresponding setting in my keyword is also demonstrated here:
  My ASCII defined the output of ELOUT/GLSTAT/MATSUM/NCFORC/NODOUT/RCFORC/SECFORC.

  I am not 100% sure since I cannot verify it against an official documentation but I believe what you plotted is like plotting triaxiality, it's just something that's calculated from other basic characteristics like principle stresses or Von mises stress.

  Thank you very much Dennis! I'll check it.

  It looks like the Ansys forum post you referenced is asking where to find the “mean IPT effective strain” in LS‑DYNA results, in LS‑Dyna, "mean IPT effective strain" isn't directly available, but you can use the effective plastic strain output, which is a monotonically increasing scalar calculated based on the plastic component of the deformation rate tensor and represents accumulated permanent deformation
