摘要
Three special forms of material functions are introduced into the Green-Rivlin constitutive equations of nonlinear viscoelasticity. Two of these reduce the third-order equations to single integral forms, rationally and experimentally derived by others. Published creep and stressrelaxation data are analysed using both the proposed and previously published constitutive equations, particular attention being given to multi-step data. Specific results show the limits of applicability of the third-order constitutive relations for the materials considered. © 1969.
