Sažetak
Two formulations of anisotropic large strain multiplicative inelasticity, taking into account that is a material tensor, are concerned. The first, non-invariant formulation is formulated using the elastic strain measure together with structural tensors defined at the referenent configuration. As it is revealed for this formulation to be non-invariant with respect to rigid body rotations superimposed on , another invariant formulation is developed. It is formulated by using the elastic strain measure together with structural tensors modified by using inelastic deformation gradient. The interrelation of the two different formulations is demonstrated by numerical example.
