Abstract:

The Christensen’s isotropic thermoviscoelastic constitutive relation is adopted to consider influence of moisture and thermal changes on the reduced time for simple thermorheological materials. The Laplace transform method is used to show that the correspondence principle for isotropic and nonhomogeneous hygro-thermo-viscoelastic quasi-static problems still holds when relaxation functions have separable forms in space and time, and the given temperature and moisture fields are only related to time variable.
