On the Temperature-Time Equivalence of Thermorheologically Simple Viscoelastic Materials

摘要

For linear stress analysis of homogeneous, isotropic, thermorheologically simple viscoelastic materials, the hypothesis of temperature-time equivalence is stated explicitly with respect to the relaxation spectra. Because relaxation spectra among the various viscoelastic functions are most closely related to the molecular processes occurring in the material, the hypothesis stated with respect to spectra is expected to indicate more clearly the validity and limitations of stress-strain relations of thermorheologically simple materials.
