A phenomenological constitutive model for rubberlike materials and its numerical applications

A new phenomenological inelastic constitutive model for rubberlike materials is presented and its good correspondence to cyclic measurements is demonstrated for both uniaxial tension- and simple shear-tests up to large deformations. The model implies strong nonlinearities, hysteresis, the influence of the loading history and remaining deformations after unloading. Results of finite element calculations are represented to show the suitability of the constitutive model within this method for practical applications.
