Sur les référentiels locaux objectifs en mécanique des milieux continus

Using the notion of objective local frame, a new objective derivative is defined for rate constitutive equations at finite strain. It is applied to the classical test of simple shear. The results obtained are discussed for isotropic hypoelasticity, rigid plasticity with kinematic hardening, and elasto-plasticity with isotropic strain-hardening. They are much simpler than those given by other rates of the same type
