Materials such as metals, ceramics, polymers, and composites are subjected to static and dynamic loads in service. Although these materials are all different, their characteristics that allow them to resist deformation and failure during loading must be known to make good design decisions, perform materials selection, and ensure quality.

Many engineers require knowledge of mechanical properties and testing to ensure that undesirable deformation and failure in a component or structure does not occur. For example, civil and structural engineers must select steels with sufficiently high strength for bridges so that excessive deformation does not occur. Similarly, an aerospace engineer may select a composite material that does not excessively deflect for use in a wing spar. A mechanical engineer may decide between stainless steels with different strengths for use in a corrosion resistant pressure vessel. On the other hand, ceramic, chemical, materials, and metallurgical engineers must understand mechanical properties, testing, and the appropriate standards to process and fabricate materials that meet the requirements of a specific application.

In this course, an overview of mechanical properties and testing is presented. This will include a review of tensile testing, three-point or four-point bend testing, hardness testing, and impact toughness testing. These tests are discussed in context of procedures, specimens, advantages, and disadvantages. The different properties that can be determined from these tests are discussed. Testing in context of industry standards is addressed. Additionally, the course covers the fundamentals of stress and strain, the differences between elastic and plastic deformation, and the differences between ductile and brittle behavior and fracture.
