Temperature influence in the description of time-dependent materials

In a previous paper, authors proposed a constitutive equation for non-linear hereditary-type materials. This equation can be extended to take into account the influence of temperature. The model is capable of describing various kinds of deformation such as monotonous tension at constant loading rate, creep and relaxation. The procedure for determining parameters is described. Seven polymer materials were investigated. A comparison of calculated and experimental results was made for these materials and these types of loading.
