Abstract

The fundamental principles of the application of fracture mechanics to rubber are briefly discussed. The importance of the problem arises because of the large nonlinear deformation of rubber which introduces difficulties in the solution of the boundary value problem of a cracked body made of rubber. The tear behavior of rubber can be conveniently described by the critical tearing energy which is a characteristic property of the material. The results of an experimental study of determining the crack growth behavior and critical tearing energies of pure tire rubber are presented. Constrained tension and trousers specimens were used for mode-I and mode-III loading, respectively. In the trousers specimens the force necessary to grow the crack varies widely from a maximum value at crack initiation to a minimum value at crack arrest. This result to a stick-slip stable crack propagation, that is, the crack arrest and reinitiates of fairly regular intervals. In the constrained tension tests crack initiation triggers catastrophic growth. Results for the critical tearing energies for mode-I and mode-III are given.
