    Abstract

    The present paper is a continuation of Part I to investigate the transverse fatigue behavior of a unidirectional titanium-based metal matrix composite (MMC) (SCS-6/Ti-15-3) at elevated temperature. In Part I of this paper, fatigue tests were conducted under the strain-controlled mode, and a systematic microscopic evaluation was undertaken to identify the damage and deformation mechanisms. In this paper (Part II), the fatigue response is modeled using a micromechanical approach where the fiber-matrix interfacial damage is incorporated along with the inelastic behavior of the matrix. The analysis provided additional insight into the transverse fatigue response of the MMC. Combining the results obtained from this micromechanical analysis, and that obtained from the macroscopic response (that is, stress and modulus) and microscopic evaluation in Part I, the transverse fatigue response of the MMC was thoroughly characterized.
