ENGR 2993: Independent Study
Credits: 1–3
Special tutorial with a topic declared in advance. The topic, work plan, and conditions are arranged by contract between instructor and student and approved by the department Chair, with a copy to be filed in the department office.
MSE 3060: Structures and Defects of Materials
Credits: 3
Basic materials structure concepts are developed, include bonding and crystallography. The structure-property paradigm is illustrated through discussion of the frequently anisotropic properties of crystalline solids, such as elastic moduli, thermal expansion, magnetic properties, and the piezoelectric effect. Descriptions of important defects in crystalline solids, from point defects, to dislocations, to interfaces are introduced along with the thermodynamic and kinetic principles that govern their interactions and roles during materials processing, such as annealing, aging, and sintering. Applications are made to a broad range of materials, from structural alloys to so-called "smart materials" used in sensors and actuators. Prerequisite: MSE 2090 and APMA 2120 or instructor permission.
MSE 4320: Origins of Mechanical Behavior
Credits: 3
Develops understanding of material deformation and fracture in response to mechanical loading. Engineering and scientific principles are integrated in an approach that includes: (a) material property phenomenology,(b) test methods, (c) causal mechanisms at the atomic defect to microstructure scale, (d) governing continuum mechanics equations, and (e) problem solving. Plastic deformation and creep are understood based on elasticity theory and dislocation concepts. Fatigue and fracture are understood based on continuum fracture mechanics and microstructural damage mechanisms. Special Topics provide capstone descriptions of content, and engage the student with future challenges and opportunities. Prerequisite: MSE 3060 or MSE 2090 plus instructor permission.
MSE 4960: Special Project in Materials Science and Engineering
Credits: 1–6
A fourth year project in MSE, under the supervision of a faculty member, is designed to give undergraduate students an application of principles learned in the classroom. The work may be experimental or computational, and the student is expected to become proficient in techniques used to process, characterize, or model materials. The project should make use of design principles in the solution of a problem. Six hours in lab per week, notebook. Prerequisite: 4th year standing and prior approval by a faculty member who is project supervisor.
MSE 6020: Defects and Microstructure in Materials
Credits: 3
Basic course designed to provide a foundation for correlating defect structure and microstructure with physical, mechanical and chemical properties of engineering materials. The fundamental properties of point, line and surface defects in ordered media will be formulated. The thermodynamics of point defects in various types of solids will be discussed as well as the geometry and mechanics of crystal dislocations and their role in crystal plasticity elucidated. The essential elements of microstructure will be characterized emphasizing the concepts of phase constitution, microconstituent, polycrystalline aggregate and multiphase materials. The concept of real materials embodying a hierarchy of structures is emphasized. The principles governing the genesis and stability of material structure at various levels will be discussed. Prerequisite: MSE 6010 and MSE 6230.
MSE 6320: Deformation and Fracture of Structural Materials
Credits: 3
Deformation and fracture are considered through integration of materials science microstructure and solid mechanics principles over a range of length scales, emphasizing the mechanical behavior of metallic-structural alloys and electronic materials. Metal deformation is understood based on elasticity theory and dislocation concepts. Fracture is understood based on continuum fracture mechanics and microstructural damage mechanisms. Additional topics include fatigue, elevated temperature behavior, material embrittlement, time-dependency, experimental design, damage-tolerant life prognosis, small-volume behavior, and material property modeling. Prerequisite: MSE 4320, or BS in MSE, or MSE 6050, or permission of instructor for graduate students outside of MSE.
