A J-integral (j) for the pointwise description of the fracture driving force along a 3-D crack front is studied for the three-point bend specimen. Results of a 3-D nonlinear finite element analysis arc used to compute J along the crack front. The analytical values are compared to experimenta\_l 'mea
