AB  - This paper assumes that the fracture energy required to separate a unit crack area along the crack growth path is influenced by the width of the fracture process zone (FPZ) at that location. This as- sumption is based on considerations of the following fracture mechanisms: friction between the uneven upper and lower crack surfaces during crack opening and crack growth, micro-crack interactions within the FPZ. Instead of using a single constant fracture energy GF for the entire projected fracture area, our present model assumes a bi-linear fracture energy distribution. GF is constant if FPZ is fully developed and is not…
