Hello,
Appendix A has an example umat41 subroutine showing how to consider material failure and subsequent element erosion. To fringe plot history variables, you will first need to have *DATABASE_EXTENT_BINARY included in the input and have the number of history variables to be extracted specified through NEIPH, NEIPS, BEAMIP for solid, shell, or beam elements respectively. Then, once you open d3plot in LSPP, go to Fringe Component > Misc and select a history variable to fringe.
I hope this helps.
