Aero Propulsion Laboratory Air Force Wright Aeronautical Laboratories Wright-Patterson Air Force Base, OH 45433 Off-axis tension tests were performed on SCS-6/Ti-6-4 metal matrix com posite. A one-parameter plasticity model was used to characterize the elastic-plastic prop erties. In addition, a micromechanical model was developed assuming elastic fiber and elastic-plastic matrix properties. This model was employed to relate the apparent yielding with the fiber/matrix separation in the MMC. From the micromechanical model, the fiber/matrix interfacial bond strength was estimated, and with the aid of a damage model, the nonlinear off-axis stress-strain curves were accurately predicted.
