Objectives:

This course focuses on the mechanical properties of materials. The lectures will emphasize stress and strain relationships how the macroscopic mechanical behavior is related to the structure and microstructure of the material. This course will discuss elementary dislocation theory and relate this to basic strengthening mechanisms. Physical and chemical mechanisms that alter the mechanical properties will be discussed. Crystalline metals and ceramics will be emphasized but polymers and non-crystalline materials will be discussed as well. Fatigue and fracture will also be discussed in terms of fundamental mechanisms.
