EMAE/EMSE 372 Relation of Materials to Design

Designing machines, vehicles, and structures that are safe, reliable, and economical requires both efficient use of materials and assurance that structural failure will not occur. This course considers the role of material selection in the design of mechanical and structural elements with respect to static failure, elastic stability, residual stresses, stress concentrations, impact, fatigue, creep, and environmental conditions on the mechanical behavior of engineering materials (metals, polymers, ceramics, composites). The professional and ethical responsibility of the engineer in this context will be considered where appropriate. Ultrastructural and microstructural aspects of materials are reviewed in terms of how they influence mechanical properties. Mechanical test methods are reviewed. Models for deformation behavior of isotropic and anisotropic materials are considered. Methods to analyze static and fatigue fracture properties are considered. Rational approaches to materials selection for new and existing designs of structures are examined. Failure analysis methods of failed structures are considered. Failure analysis examples of actual failed structures will be discussed and the professional and ethical responsibility of the engineer will be considered.  This course has a laboratory component.
