Evaluation of the stress intensity factor for cracks in elastomers
We analyze the applicability of the method of the J-integral to the solution of problems of fracture mechanics for structures made of low-compressible elastomers. The components of the J-integral are computed by the method of equivalent three-dimensional integration. To take into account weak compressibility, we use the finite-element moment scheme.
