| Abstract |
This paper is devoted to a method for the construction of constitutive relations for an isotropic solid. The method proposed here does not require the traditional a priori assumption of the mathematical structure of these relations or the form of the energy function, from which the constitutive relations would follow. It is shown that for the energy functions for an arbitrary stress state to be able to be uniquely defined, it is necessary and sufficient to have data obtained from two basic experiments. Constitutive relations adequately describing nonlinear effects in deformable solids are obtained (these effects are connected with tensor nonlinearities of these relations). Conditions are found for these relations to become tensor-linear. When deriving the system of governing equations, some specific properties of the logarithmic strain tensor, through which the law of state is expressed, are taken into account. In the case of small elastic strains, physically linear constitutive relations are obtained. These relations, in contrast to the corresponding constitutive relations of the classical elasticity, describe second-order geometric effects in the case of elastic deformation of isotropic solids. |
