• Based on the nonlinear isotropic elastic constitutive equations represented by tensor, a complete polynomial thermal stress constitutive equation and strain energy function of nonlinear isotropic elastic material were proposed. Just the initial temperature and the increase value were considered. As an application example, using MATLAB software, results were compared with known experimental data for hightemperature metal materials under uniaxial tension and compression of the elastic stage, which showed a good agreement with the results of the proposed theoretical model.
