MS4811 Mechanical Behavior of Engineering Materials

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.

Course 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.
