Stress-Free Joints and Polycrystals
Suppose two or more stress-free homogeneous solid bodies are joined firmly together along various surfaces at a temperature θ0. As the temperature is changed, the joined body will deform in some way with null traction at its boundary. Generally, we expect the joined body to build up stress unless some special conditions are satisfied by the orientation and constitution of the bodies, and by the shapes of the dividing surfaces.
