Overview

The response of structural materials to stress is discussed, including elastic and plastic deformation and fracture. Topics include elastic response and the modules of elasticity; plasticity; deformation mechanisms and dislocation theory; strengthening mechanisms; and fatigue and fracture. Application to materials development is also considered.

Learning Outcomes

• Calculate quantities such as elastic modulus, equilibrium bond distance, and bonding energy from a diatomic bonding curve.
• Describe how different types of bonding give different thermo-elastic responses.
• Manipulate and use tensors to calculate elastic properties in anisotropic materials.
• Describe the basic types and crystallography of dislocations in the FCC, BCC, HCP metallic structures.
• Be able to calculate the physical quantities of dislocations including self-energies, interaction forces, bowing forces and stresses, and reaction energies.
• Be able to qualitatively and quantitatively compare and contrast the four basic strengthening strategies for metallic alloys.
• Quantitatively analyze data from tensile testing experiment to extract quantities such as yield strength, ultimate tensile strength, and elastic modulus.
• Construct and use deformation mechanism maps to predict the high temperature behavior of metallic and ceramic materials.
