Book Description
Two specimen configurations of a [0/90]2s SCS-6/Ti-15-3 laminate were tested and analyzed: a center-hole (CH) specimen and a double-edge-notched (DEN) specimen. The two specimen configurations failed at similar stress levels in spite of the large difference in the stress concentration factors for the two geometries. Microscopic examinations of the failure surfaces indicated more fiber-matrix debonding at the notch tip in the DEN specimen than in the CH specimen. Based on the experimental results, it was hypothesized that the radial stresses that developed at the fiber-matrix interface ahead of the notch tip in the DEN specimen caused fiber-matrix debonding in the 0° plies, thus lowering the stress concentration in the DEN specimen to a level comparable to that of the CH specimen.

Book Description
An investigation was undertaken to evaluate the constitutive response and in-elastic deformation characteristics in titanium-based metal matrix composites (MMC) with two types of ceramic fibers, namely, SCS-6 and Sigma. The titanium matrix was Beta 21S, currently named TIMETAL-21S. Monotonic tests were conducted at room temperature (RT) and between 483 and 815°C. The inelastic deformation in the [0]8 lamina under compression was controlled primarily by matrix plasticity, although some evidence of fiber-matrix debonding was observed. The inelastic deformation mechanisms under compression in [90]8 lamina were primarily due to radial fiber cracking from the core for the SCS-6 fiber and fiber-matrix debonding. However, for the Sigma fiber, radial cracking was absent. The effect of temperature on degradation of mechanical properties such as modulus and yield strength for the composites with two different fibers were compared.
