Novel (non-quadratic) plasticity criteria based on Kelvin modes are formulated here for anisotropic materials. As an example, such a macroscopic criterion is applied with success to the case of FCC nickel-base single crystals. Indeed, relying on the…

Non-saturating nonlinear kinematic hardening laws

To compensate the drawback of most kinematic hardening laws who exhibit hardening saturation, a solution is proposed by replacing the accumulated plastic strain rate in the springback term by a rate related to the kinematic hardening variable itself…

Kelvin decomposition and multiple effective stresses concept in anisotropic materials

The effective stress concept, now classical in continuum damage mechanics, is generalized to the case of an initial anisotropy. In order to be used for both damage–elasticity and damage–(visco-)plasticity coupling, the effective stress should not…
