Abstract
Mode I crack propagation in fiber reinforced cementitious composite is simulated based on fracture mechanics criteria. To analyze crack propagation, a superposition method is employed to calculate the stress intensity factor at the crack tip resulted from both the applied load and the crack bridging stress. Using the model, the effects of various material parameters on the tensile performance are investigated. The requirements for tensile strain-hardening and multiple cracking are analyzed and possible methods for material performance optimization are discussed. Finally, predicted behavior is verified by tensile and bending tests performed on two fiber reinforced cementitious composite beams.
