LS-DYNA Research - ResearchGate

I am writing a UMAT for LS-Dyna (in fortran 77) for a cyclic load-unload condition, with isotropic hardening. The problem is, how do I store the final stress (before unloading) and then using it as input for the next variable? In ABAQUS, a statement called statev is available, however, I am not sure of a counterpart for LS-Dyna.
