Design diagrams for reliable layered materials

Design diagrams for reliable layered materials
Design diagrams for reliable layered materials
Many components and structures consist of two or more layers of dissimilar materials bonded together overareas 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 two layered 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 identified 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 and manufacture of layered materials. The same graphical format can be used to map performance metrics relevant to functional requirements other than reliability, such as heat flow, curvature, and mass per unit area. These diagrams are potentially useful for the preliminary design of components with multiple performance requirements.

Abstract

Many components and structures consist of two or more layers of dissimilar materials bonded together overareas 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 two layered 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 identified 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 and manufacture of layered materials. The same graphical format can be used to map performance metrics relevant to functional requirements other than reliability, such as heat flow, curvature, and mass per unit area. These diagrams are potentially useful for the preliminary design of components with multiple performance requirements.
