The present invention describes a superelastic constitutive of rubber material Model modeling method. In this method, the influence model of polymer molecular chain volume is first proposed. Then the eight-chain model is improved and the probability density function caused by topological constraints is proposed. Then the relationship between microscopic deformation and macro-deformation of molecular chain is established, Density function, a non-affine hyperelastic constitutive model is obtained. The present invention establishes a rubber material
