Research Abstract

We designed an experimental system of the crack of thin rubber films coupled with viscous fluid layer to realize slow fracture compared to sound propagation. We found a transition in the crack dynamics exhibiting oscillatory to straight patterns. Based on numerical simulations as well as experiments, we concluded that such oscillating patterns can not be explained within the framework of the conventional linear fracture mechanics and nonlinear elasticity due to largely deformation of rubber films is the essential factor.
