A model of multiplicative ยฎnite strain viscoplasticity is developed. Hereby the elastic internal potential is assumed to depend quadratically on the elastic strain measure C e by means of corresponding invariants. Hence, possible extension of the model to take anisotropy into account is straightforw

In contrast to multiplicative models of finite strain plasticity and viscoplasticity, a framework of additive nature is developed in this paper. The theory is based on the additive decomposition of the logarithmic strain tensor. The stress conjugate to the logarithmic strain then plays the role of t
