Abstract

The mechanical and fatigue behavior of different rubber compounds is investigated under multi-axial loading mode by means of a dedicated multi-axial device. The stress-strain behavior has been also interpreted using several constitutive models, both hyperelastic and viscoelastic. The fatigue behavior has been judged using 1) the classical energetic approach and 2) a new methodology based on the combination of J-integral approach and digital image correlation technique (DIC) whose general validity makes it suitable for the interpretation of fatigue data under general loading mode.
