08F, 09F: 9 A study of the mechanical properties of engineering materials and the influence of these properties on the design process. Topics include tensorial description of stress and strain, elasticity, plastic yielding under multiaxial loading, flow rules for large plastic strains, microscopic basis for plasticity, viscoelastic deformation of polymers, creep, fatigue, and fracture. Prerequisite: Engineering Sciences 24 and 33, or equivalent. Schulson.

08F, 09F: 10; Laboratory This course provides a background in solid state physics and gives students information about modern directions in research and application of solid state science. The course serves as a foundation for more advanced and specialized courses in the engineering of solid state devices and the properties of materials. The main subjects considered are crystal structure, elastic waves-phonones, Fermi-Dirac and Bose-Einstein statistics, lattice heat capacity and thermal conductivity, electrons in crystals, electron gas heat capacity and thermal conductivity, metals, semiconductors, superconductors, dielectric and magnetic properties, and optical properties. Amorphous solids, recombination, photoconductivity, photoluminescence, injection currents, semiconductor lasers, high temperature superconductors, and elements of semiconductor and superconductor microelectronics are considered as examples. Prerequisite: Engineering Sciences 24 or equivalent. Petrenko.

09W, 10W: 11; Laboratory This course discusses the thermodynamics and kinetics of phase changes and transport in condensed matter, with the objective of understanding the microstructure of both natural and engineered materials. Topics include phase equilibria, atomic diffusion, interfacial effects, nucleation and growth, solidification of one-component and two-component systems, solubility, precipitation of gases and solids from supersaturated solutions, grain growth, and particle coarsening. Both diffusion-assisted and diffusionless or martensitic transformations are addressed. The emphasis is on fundamentals. Applications span the breadth of engineering, including topics such as polymer transformations, heat treatment of metals, processing of ceramics and semiconductors. Term paper. Prerequisite: Engineering Sciences 24 and 25, or equivalent. Schulson.

Not offered in the period from 08F through 10S This course discusses both the theoretical background and practical applications of x-ray diffraction and topography, and transmission electron diffraction and microscopy for examining the structure of materials. Topics include: phase-contrast imaging, diffraction contrast, kinematical and dynamical theories of diffraction, weak-beam imaging, image simulation, convergent-beam electron diffraction, phase identification, orientation determination, structure determination. Practical work consists of four laboratory sessions, each of which requires a short report. Prerequisite: Engineering Sciences 24 or permission.

09W: 10A; Laboratory Offered in alternate years A graduate section of Engineering Sciences 74 involving additional class meetings, some of which will be in a journal club format. Current papers in the field of nanotechnology will be discussed in the context of the course material. In the second half of the term, students will pick a topic of interest and have either individual or small group meetings to discuss literature and research opportunities in this area. The students will prepare a grant proposal in their area of interest. Not open to students who have taken Engineering Sciences 74. Prerequisites: Engineering Sciences 24 or Physics 19 or Chemistry 6, or equivalent. Gibson.

10W: Arrange Offered in alternate years This course covers the processing aspects of semiconductor and thin film devices. Growth methods, metallization, doping, insulator deposition, patterning, and analysis are covered. There are two major projects associated with the course -an experimental investigation performed in an area related to the student's research or interests, and a written and oral report on an area of thin film technology.Prerequisite: Engineering Sciences 24 or equivalent. Gibson, Levey.

09S, 10S: 2A This survey course discusses both the physical principles and practical applications of the more common modern methods of materials characterization. It covers techniques of both microstructural analysis (OM, SEM, TEM, electron diffraction, XRD), and microchemical characterization (EDS, XPS, AES, SIMS, NMR, RBS and Raman spectroscopy), together with various scanning probe microscopy techniques (AFM, STM, EFM and MFM). Emphasis is placed on both the information that can be obtained together with the limitations of each technique. The course has a substantial laboratory component, including a project involving written and oral reports, and requires a term paper. Prerequisite: Engineering Sciences 24 or permission. I. Baker.

3.00 Credits
09W, 10W: 2 The fundamentals of dynamics with emphasis on their application to engineering problems. Newtonian mechanics including kinematics and kinetics of particles and rigid bodies, work, energy, impulse, and momentum. Intermediate topics will include Lagrange's equations, energy methods, Euler's equations, rigid body dynamics, and the theory of small oscillations.Prerequisite: Engineering Sciences 22. Van Citters.

3.00 Credits
09W, 10W: 10 Exact and approximate solutions of the equations of elasticity are developed and applied to the study of stress and deformation in structural and mechanical elements. The topics will include energy methods, advanced problems in torsion and bending, stress concentrations, elastic waves and vibrations, and rotating bodies. Although most applications will involve elastic deformation, post-yield behavior of elastic-perfectly plastic bodies will also be studied. The course will also include numerous applications of finite element methods in solid mechanics. Prerequisite: Engineering Sciences 33 or permission of the instructor. May.

3.00 Credits
09S, 10S: 10A A continuation of Engineering Sciences 26, with emphasis on digital control, state-space analysis and design, and optimal control of dynamic systems. Topics include review of classical control theory; discrete-time system theory; discrete modeling of continuous-time systems; transform methods for digital control design; the state-space approach to control system design; optimal control; effects of quantization and sampling rate on performance of digital control systems. Laboratory exercises reinforce the major concepts; the ability to program a computer in a high-level language is assumed. Prerequisite: Engineering Sciences 26. Phan.
