Abstract : The rubbery environments present the same mechanical behaviour as hyperelastic or viscohyperelastic material. Regarding the filled-elastomers, the high degree of deformability often generate microscopic and voluminal defects leading to the creation of micro-cracks inside the structure. It is important to develop sophisticated models to take into account the various physical phenomena and particularly the degradation of the matter by damage (or Mullins effect). The proposed approach is used to couple material degradation by damage with permanent strain in filled-elastomer materials. The efficiency of the method is validate with some examples.
