A fracture mechanics based theoretical model is presented to predict the crack propagation resistance of steel fiber reinforced cement based composites. Mode I crack propagation and steel fibers are treated in the proposed model. The mechanism of fracture resistance for FRC can be separated as: subcritical crack growth in matrix and beginning of fiber bridging effect; post critical crack growth in matrix such that the net stress intensity factor due to the applied load and the fiber bridging closing stresses remain constant; and a final stage where the resistance to crack separation is provided exclusively by fibers. The response of FRC during all these stages was successfully predicted from the knowledge of matrix fracture properties and the pull-out load vs. slip ( sigma - omega ) relationship of single fiber. The model was verified with the results of experiments conducted on notched-beams reported here as well as by other researchers.
