Official Description
Detailed Course Description
Micromechanisms at the atomic, single-crystal, and polycrystal levels and their use in explaining the deformation and failure characteristics of metals; elastic deformation, dislocation mechanics, plastic deformation and strengthening mechanisms, fracture mechanics and fracture mechanisms, fatigue, and creep; design criteria; special topics. Prerequisite: TAM 324/CEE 300 or ME 330; or consent of instructor. 3 undergraduate hours.
Topics:
Introduction (5 hr)
Overview; materials classification; typical microstructural constituents--grains, phases, particles, etc.; stress, strain and simple tension experiments
Elastic deformation (4 hr)
Unit cells of crystalline materials; Hooke|#39;s law, physical basis of linear elasticity; anisotropic linear elasticity; elastic properties of heterogeneous media
Dislocation mechanics (8 hr)
Ideal shear strength of perfect crystals; topology and properties of dislocations; generation of dislocations and resultant permanent deformation; dislocation interaction with other dislocations and with other defects
Plastic deformation and strengthening mechanisms (6 hr)
Critical resolved shear stress in single crystals; plastic deformation in polycrystals; strengthening mechanisms; plastic yielding under complex stress states; limit analysis
Fracture mechanics and fracture mechanisms (8 hr)
Linear elastic fracture mechanics, ideal tensile strength of perfect crystals, brittle fracture mechanisms; elastic-plastic fracture mechanics, ductile fracture mechanisms; ductile-to-brittle transition in fracture; creep fracture mechanisms; failure of composites
