AB  - For beams made of quasi-brittle materials, the moment can increase after a crack starts to propagate so the formation of multiple cracks is possible. Here, an energy minimization based method is proposed to determine the pattern of multiple cracking in such beam under pure bending. The fracture behavior of quasi-brittle material is described through cohesive zone model (CZM) with a linear softening law. Assuming the presence of a periodic and parallel crack array in the beam, the effects of crack spacing and beam curvature on the total energy per unit length of the member is obtained through finite element (FE)…
