Monotonic Response

The deformation and failure characteristics of metal matrix composites (MMCs) reinforced with silicon carbide (SiC) fibers, such as SCS-6, are significantly different from the pure matrix material because of the interaction of damage entities with ensuing matrix plasticity. This chapter discusses unidirectional properties of MMCs and their deformation response in tension, compression, and shear with primary focus on room temperature response. Limited discussion on elevated temperature response is forwarded. Some analytical aspects are discussed along with supporting experimental results to develop a comprehensive understanding of the behavior of continuous fiber MMCs. The results presented in the chapter suggest that the monotonic response of [0]8 and [90]8 laminae and [±45]2s laminate retain similar characteristics at elevated temperature compared with what is observed at room temperature.
