We conduct a finite element analysis of the slice compression test (Shafry, Brandon and Terasaki, 1989) applied to metal-matrix composites. This test, designed to characterize interfaces in composite materials, involves pressing a composite material specimen on a soft plate so that fibers are forced to protrude and intrude into the soft plate leaving a permanent deformation. We focus on the Ti-6Al-4V matrix with SCS-6 silicon carbide fibers composite system. We conduct clauclations using ABAQUS and emply contact elements at the fiber-matrix interface which incorporate a stress-based criterion for crck initiation and frictional slipping. The analysis is performed in three stages; i) thermal analysis accounting for thermal residual stresses, ii) mechanical loading, and iii) mechanical ulnloading. The fiber protrusion length, permanent indent depth in the base matieral, and the debonding length along the fiber-matrix interface are the main output parameters.
