✦ Synopsis

The creep hardening constitutive model based on the concept of kinematic and isotropic hardening, and the memory of maximal prestress, developed in Ik~Oz ~ Tt~aocz,~sla [1984], is modified and extended in order to increase its simplicity and to describe creep-plasticity interaction programs. Next, the model is applied to the case of cyclic creep deformation in pure copper tubes subjected to combined tension and torsion at 300°C and to cyclic creep of 304 stainless steel at 600°C for varying complex stress levels.
