Abstract
Understanding the deformation of eutectic composites under conditions of changing temperature with or without externally applied loading is important to the utilization of these materials. Here a method of calculating elastic-plastic deformation parameters in such materials is derived and its use demonstrated. The method uses stress equilibrium, strain continuity, and component constitutive relations to derive expressions for matrix stress as a function of temperature during heating and cooling or hold time at constant temperature. From that quantity several deformation parameters of interest can be calculated. Because numerical techniques must be used to determine solutions, great flexibility is available in the selection of cycling conditions and material constants. An illustrative calculation is presented and its results are discussed.
