Studies on a local criterion for crack initiation on a vulcanized filled elastomer

摘要: Nowadays,the estimation of fatigue crack initiation industrial parts presents growing economic interest. Usually, life predictions in rubber studies are given by a component stress or strain tensor according to the number cycles. This often involves difficulties due complexity states. Our paper proposes establish simple visco-hyperelastic model. These equations are, then, implemented Finite Elements code, which will give local information on and states particular intrinsic dissipation. Then, maximum dissipation integrated over one cycle is proposed as criterion.
