2. Elastoviscoplasticity and thermophysical coupling

The elasticity and strain-hardening of the material can be taken into account when hot, as described in § 1 and 2 of the [17] file. In the case of work-hardening, the consistency K of the (3) relationships evolves with the generalized deformation of the material for isotropic work-hardening, and it may be necessary to introduce a kinematic tensor X into the expression of the criterion to take account of the kinematic work-hardening component.

When hot, plastic flow stress...
