摘要：

A method for estimating the fracture toughness of rubber-like materials is presented. Experimental data of a notched natural rubber sheet is analyzed by application of the path-independent J-integral. A finite element code for large elastic deformations is used to evaluate the deformed shape of the rubber at crack growth initiation. Discussed is a stability criterion based on the existence of a critical value of J in relation with the experimental results.
