ABSTRACT
The extensive applications of elastomers in industry and civil elds nowadays motivate many investigations dealing with continuum mechanics and material science on rubbers. Usually the used rubbers are lled with active llers like carbon black or silica. The ller-aggregates con gurations are arranged in order to enhance essential properties like sti ness, strength, abrasion resistance, fatigue lifetime… Many constitutive studies focused on both Payne and Mullins’ e ects the main characteristic of which is the stress-softening related to nonlinearities induced by strain.
