      nHi Array nPlastic work per volume is the same as plastic strain energy density. nl, plwk and send, plastic should produce same resultsn NL (nonlinear) records existed for many years, and NL,PLWK was used by the older VISCO10x (viscoplastic, not viscoelastic) elements. nWhen 18x elements were introduced they had a SEND record. Legacy elements do not use SEND. The SEND records are only written when NLGEOM,ON is set. They include elastic, plastic, and creep strain energy density (i.e., work/volume). nn
