Hello, so nlplwk is the non-linear plastic work per unit volume. nl does not indicated nodal. This quantity already has the volume accounted for, so no need to do anything further. It can be compared to the modulus of toughness of a material. If you do a search on modulus of toughness you will find detailed explanation. So this can be used to get a sense of how much strain energy per unit volume the material can withstand before fracture. It can also be used in fatigue applications and with solder that can be common.nSo if you make a contour plot you can see the contour of value and you can compare it to the modulus of toughness. Let us know if this answers your question.nnThank younSann
