Краткое описание

A model of the mechanical behavior of rubber is considered. For constructing the governing equation, a scheme whose points are connected by elastic, viscous, plastic, and transmission elements is used. To describe the properties of each of the elements, the well-known equations of the nonlinear theory of elasticity, of the theory of nonlinear viscous fluids, and of the theory of plastic flow of a material under the conditions of the finite deformations of a medium are employed. An algorithm for obtaining the constants of the model is suggested. The search for these constants is arranged in steps. The constants in the governing equations determined at the previous step do not change at subsequent ones. The experiments (cyclic loadings with relaxation and creep) allow one to obtain more information on the viscoelastic properties of rubber.
