Abstract: Abstract It is a matter of fact that creep experiments can be conducted more easily and accurately than stress relaxation experiments, since it is easier to maintain a stress constant (for instance by a “dead weight”) than a strain constant. Nevertheless, in practice, structural parts made of plastics (which are nonlinear viscoelastic materials) are very often loaded under stress‐relaxation conditions. The present paper presents an approach to predict the behavior of a nonlinear viscoelastic material under st…
