Experimental Observation of Induced Anisotropy of the Mullins effect in particle-reinforced silicone rubber
Résumé
This study deals with the experimental characterization of anisotropy induced by the Mullins effect in a filled silicone rubber. Uniaxial tensile tests and biaxial tests (by means of a bulge test) were used to precondition the samples. In the two cases, subsequent uniaxial tensile tests were performed on preconditioned specimens. Two different strain histories were defined: first uniaxial tension followed by uniaxial tension along different directions and second biaxial tension followed by uniaxial tension.
