Abstract

A fracture mechanics approach for the pullout of a short fiber from a cementitious matrix is developed. The interfacial zone is characterized as an elastic-perfectly plastic 1-D layer. Stable debonding was modelled as an R-curve behavior with toughness increasing as the debonded length increases. The strain energy release rate of a partially debonded frictional interface is used to solve for the R-curve parameters and the load-slip response. Effects of fiber length, diameter, interfacial strength, and tensile strength are studied.
