abstract
Recently, taking the Second-Law of Thermodynamics as a starting point, a theoretical framework for an exact calculation of the elastothermodynamic damping in metal-matrix composites has been presented by the authors (Kinra and Milligan, 1993; Milligan and Kinra, 1993). Using this work as a foundation, we calculate the elastothermodynamic damping for two canonical boundary-value problems concerning continuous-fiber reinforced metal-matrix composites: (1) a fiber in an infinite matrix, and (2) using the general methodology given by Bishop and Kinra (1993), a fiber in a finite matrix. In both cases the solutions were obtained for the following loading conditions: (1) uniform radial stress, and (2) uniform axial strain.
