Abstract

A fully three- dimensional finite- strain viscoelastic model is developed, characterized by: (1) general anisotropic response; (II) uncoupled bulk and deviatoric response over any range of deformations;III general relaxation functions; and (IV) recovery of finite elasticity for very fast or very slow processes; in particular, classical models of rubber elasticity. A numerical integration procedure is presented which preserves exactly the principle of objectivity and by- passes the use of mid- point configurations.
