摘要
Based on the concept of thermoelasticity in a single-phase elastic solid, we have investigated thermal stresses in a two-phase composite media. A two-phase composite slab and a concentric solid sphere were considered. The temperature distribution has been obtained by means of the Laplace transform. General formulas of thermal stresses in two- phase composite are derived, and numerical examples are provided. For a constant average temperature and a constant surface temperature, the maximum transverse (or tangential) stress is located at the surface for both slab and sphere. © 1995 Taylor & Francis Group, LLC.
