Identification of interfacial parameters with analytical and numerical models from Pull-out tests on a micro-composite

This paper deals with the identification of interfacial parameters of SiC/Pyrex composite from Pull-out tests. The response load versus crack opening displacement of a monofilament bridging a matrix crack is measured. It is analysed using a classical model developed by Marshall which takes roughness effects into account. We focus attention on both the unloading/reloading cycles and monotonic loading. A Finite Element analysis is also presented and compared to analytical solutions. The two approaches are in agreement but are unable to model a whole test with a single set of parameters.
