✦ Synopsis

The J-integral is derived for mode I and mode II cracks in orthotropic composite materials and it is shown to be independent of the integral path around the crack tip. The J-integral is then extended and applied to a newly developed energy based fracture criterion for orthotropic composite materials and then applied to the mixed mode fracture analysis of composites.
