摘要: A new constitutive model is derived for the nonlinear viscoelastic behavior of polymers which do not possess separability property. The based on concept adaptive links (a version theory transient networks). It assumed that response a link essentially nonlinear, and rates breakage reformation depend strain intensity. With reference to Eyring thermally activated processes, equation proposed describe effect strains links. Adjustable parameters are found by using experimental data polycarbonate an epoxy glass in standard relaxation tests. Comparison dynamic tests with results numerical simulation shows correctly predicts response.
