Many components and structures consist of two or more layers of dissimilar materials bonded together over areas that are large relative to the layer thickness. A methodology is presented that is appropriate for designing against failure due to thermomechanical loading in these systems. Results are presented for the fracture of twol ayered systems of elastic materials under uniform thermal loading. In such a system of two or more materials, failure occurs as the result of four competing fracture modes. This competition is assessed, and the conditions are identifed for one fracture mode to occur in preference to the others. The results are presented as fracture mechanism diagrams, which give easily interpreted guidance for the design andmanufacture of layeredmaterials. The same graphical format can be used to map performance metrics relevant to functional requirements other than reliability, such as heat flow, curvature, andmass per unit area. These diagrams are potentially useful for the preliminary design of components with multiple performance requirements.
