Mechanical Behavior of Materials

ME 56900 / 3 Cr. (3 Class)

How loading and environmental conditions can influence the behavior of materials in service. Elastic and plastic behavior, fracture, fatigue, low- and high-temperature behavior. Introduction to fracture mechanics. Emphasis is on methods of treating these conditions in design.

Primary Track: Solid Mechanics & CAE, Materials
