Use of a One-Parameter Family of Gordon-Schowalter Objective Derivatives to Describe Finite Strains of Viscoelastic Bodies

摘要

AbstractA constitutive relation is considered for viscoelastic materials at finite strains. This relation is obtained using a one-parameter family of Gordon–Schowalter objective derivatives and generalizes the elementary Maxwell model. It is shown that, in the problem of simple shear of an incompressible viscoelastic material, this constitutive relation allows one to obtain the Poynting effect for any parameters of the model.
