Abstract
In this paper, we obtain the rate-type constitutive expressions of the nonlinear isotropic elasticity by using the Jaumann, Truesdell and Green-Naghdi stress rate respectively. Through analysing the simple shear deformation for Mooney-Rivlin material, three kinds of rate-type constitutive equations are verified to be equivalent to the original equation. Rate-type variational principles are also presented, and the Ritz method is used to obtain the numerical solution of a rectangular rubber membrane under uniaxial stretch.
