Teaching MS/ME 161. Imperfections in Crystals. 9 units (3-0-6); third term. Prerequisites: Graduate standing or MS 115 a. The relation of lattice defects (vacancies, interstitials, dislocations) to the physical and mechanical properties of crystalline solids. Introduction to point imperfections, and their relationships to transport properties in metallic, covalent, and ionic crystals. Kroeger-Vink notation. Introduction to dislocations: geometric, crystallographic, elastic, and energetic properties of dislocations. Dislocation reactions and interactions including formation of locks, stacking faults, and surface effects. Relations between collective dislocation behavior and mechanical properties of crystals. Introduction to computer simulations of dislocations. Grain boundaries. The structure and properties of interfaces in solids. Emphasis on materials science aspects of role of defects in electrical, morphological, optical, and mechanical properties of solids.
MS/ME 162. Mechanical Behavior of Materials. 9 units (3-0-6); first term. Prerequisites: MS/ME161 a or equivalent. Introduction to the mechanical behavior of solids, emphasizing the relationships between microstructure, defects, and mechanical properties. Elastic, anelastic, and plastic properties of crystalline and amorphous materials. Polymer and glass properties: viscoelasticity, flow, and strain rate dependence. The relations between stress, strain, strain rate, and temperature for deformable solids. Application of dislocation theory to strengthening mechanisms in crystalline solids. The phenomena of creep, fracture, and fatigue and their controlling mechanisms.
Ae244. Mechanics of Nanomaterials This course will cover the basics of the mechanics of both nano-structures and nano-structured materials. Synthesis and processing methods, analytical characterization techniques, and resulting material properties and applications will be covered. The emphasis will be on relation between micro-structural and mechanical properties. Specifically, the course will give an overview of properties of nanostructured metals/ceramics/composites, nanowires, nanotubes, quantum dots, and nano-particles with their applications in electronics, sensors, and bio-medicine. Innovative experimental methods, atomistic simulations, and microstructural characterization techniques developed for studying nanoscale phenomena will be described. Recent advances in the application of nanomaterials in engineering systems and IP-related aspects of nano-materials will also be covered.
