Evaluation of interfacial properties of fiber-reinforced ceramic composites using fiber push-in tests
Evaluation of the interfacial properties of fiber-reinforced ceramic composites using fiber push-in tests is addressed. The stress-displacement relation of the embedded fiber subjected to an axial loading-unloading cycle is analyzed. The interfacial bonding, Coulomb friction at the debonded interface, Poisson's. effect of the loaded fiber, and residual stresses are included in the analysis, and closed-form analytical solutions are obtained. Based on the analytical solutions, a methodology is established to extract the interfacial properties from the experimental stress-displacement curves. Roles of interfacial bonding, Poisson's effect, and residual axial stresses on residual fiber displacement after complete unloading are also addressed in the present study.
