      There is no direct way to define a single material model with a modulus that increases with heat up and increases further with subsequent cool down. But there can be some work around for this; 1) One can try setting up a duplicate material set that represents the modulus during the cool down step? Then run LS1 for the heatup with mat1, execute EMODIF to change the material attribute number (=mat2) after heat up is complete and then restart at LS2 for the cooldown step. 2) Alternately, maybe one could program own material behavior via USERMAT.
