CONTENT

Study of the deformation of solids under stress; emphasizing the role of imperfections, state of stress, temperature and strain rate. Stress, strain, and the basic concepts of deformation and fracture for metals, polymers, and ceramics; analysis of important mechanical properties such as plastic flow, creep, fatigue, fracture toughness, and rupture. Application of these principles to the design of improved materials and engineering structures. Emphasizes the relationships between microscopic mechanisms and macroscopic behavior of materials.

OBJECTIVE

To enhance the understanding of the fundamental knowledge of mechanical responses in engineering materials, deformation mechanisms and failure modes upon the application of loads, and incorporate failure criteria in design of engineering structures.

LEARNING OUTCOME

By the end of this course, the students should be able to:
Differentiate failure by deformation and fracture
Classify materials mechanical behavior by their spatial and directional dependence
Plan mechanical tests for characterization
Assess the materials mechanical behavior by the basic test data
Know the stress-strain relation for linear elastic materials with different material symmetries
Study stress and strain transformation
Determine principal stress and strains and associated directions
Derive and calculate various elastic properties of composites from the properties of constituents through using mixture rules/assumptions
Understand failure criteria for ductile and brittle materials
Understand the basics of fracture mechanics
Implement failure criteria in design of engineering structures
