(OP)
Hi everyone,
I have a question about UMAT, how many terms I have to define, will DDSDDE + STRESS be enough? And what's for to define SSE? Just for output?
Thanks,

RE: about ABAQUS/UMAT
the Jacobian matrix ,DDSDDE, and the the vector containing the stress components ,STRESS, do suffice.
Anyway, specific strain energy SSE is not mandatory for the solution therefore you may skip its computation within UMAT.
