The present paper deals with the continuum mechanical modeling of Mullins effect observed in swollen rubber under cyclic loading conditions. For this purpose, the concept of Continuum Damage Mechanics (CDM) applied to rubber materials is adopted and extended in order to take into account the swelling level. The damage exhibited by the material due to Mullins effect is assumed to be isotropic and is described by a scalar damage parameter which depends on the swelling level and on the maximum deformation experienced by the material during loading history. Results show that the proposed model is qualitatively in good agreement with experimental observations.
