For problems involving composite bodies composed of two or more materials, the elasticity solution requires both boundary

Question:

For problems involving composite bodies composed of two or more materials, the elasticity solution requires both boundary conditions and interface conditions between each material system. The solution process is then developed independently for each material by satisfying how the various material parts are held together. The composite bodies shown are composed of two different materials, (1) and (2), that are perfectly bonded thereby requiring displacement and stress continuity across the interface. Establish the required boundary and interface conditions for each problem.
