Concrete Fracture Models and Applications 64 we realized that the mostCementitious materials, rocks and fibre reinforced composites commonly termed as quasibrittle , need a different fracture mechanics approach to model the crack propagation study because of the presence of significant size of fracture process zone ahead of the crack tip. Recent studies show that concrete structures manifest three important stages in fracture process: crack initiation, stable crack propagation and unstable fracture or failure. Fracture
