Fracture of an inhomogeneous cantilever beam whit two internal parallel lengthwise cracks is analyzed. Cracks have different lengths and are located arbitrary along the beam width. The beam exhibits continuous material inhomogeneity in both width and length directions. The fracture is studied in terms of the strain energy release rate. For this purpose, the beam is treated as a structure with two degrees of internal static indeterminacy. The solutions to the strain energy release rate, derived in the present paper, are verified by the using the J-integral approach. A parametric investigation of the lengthwise fracture behaviour of the beam is performed.
