[img_assist|nid=12469|title=Modelling high temperature behaviour of intermetallic alloy with Abaqus|desc=Hi, I'm working on modelling the behaviour of an intermetallic alloy at high temperatures i.e. 700 - 900 oC. One of the curves generated from a uniaxial tensile test at 800 oC is attached. There is a sharp drop in stress after yielding before plastic deformation occurs. Does a continuum constitutive law exist that might be able to model this in Abaqus? Any help is much appreciated. Thanks. Eoghan|link=none|align=left|width=100|height=66]
