Defining Anisotrpic Creep Material in Abaqus.
I have uniaxial and biaxial creep test datas (time vs creep starin). How can I find the the uniaxial equivalent deviatoric stress (q) to use it in ABAQUS solver.
I dont quite understand what you are trying to do
What model are you planning on using?
Also note that the PolyUMod library can predict anisotropic creep.
