Mechanical, Materials, and Structure Engineering Engineering Microcourses
E247: An Introduction to Aerodynamics
E242: Introduction to Composite Materials
Imagine a material that can offer mechanical properties competitive with aluminum and steel but are at fractions of their weight – a type of material with that capability are composites. Composite materials are used for many applications such as aircraft structures, biomedical devices, racing car bodies, and many others for their capability of possessing more balanced properties (stronger, tougher, lighter, etc.) when compared to traditional materials. In this class, students will delve into the theory to design composite structures, processing techniques to manufacture them, and structural testing methods for validation. Starting from traditional fiber-reinforced composite materials, this course will also bring in new concepts such as nanocomposites and bioinspired composites.
E244A: Mechanical Behavior of Engineering Materials
The main goal is to provide students with a basic understanding of linear and nonlinear elastic behavior, deformation under multiaxial loading, plastic deformation and yield criteria, strain hardening, strengthening mechanisms, stress concentration effects, fracture mechanisms, brittle and ductile fracture, and low-cycle/high-cycle fatigue. This course will cover failure by plastic deformation, fracture, fatigue, and environmental factors. Specific topics include engineering material characteristics, heat treatment, dislocations/defects, structure-property relations, multiaxial loading, yield criteria, strengthening processes, stress concentration effects on fracture and fatigue life, ductile versus brittle fracture.

E246B: Surface Engineering
This course is concerned with interacting surfaces in relative motion under various settings, including traditional engineering (e.g., bearings, gears, guideways, metal forming and machining), microelectronics (e.g., MEMS devices), and biotechnology (e.g., implantable components, such as total joint replacements, stents, and intra-vessel catheterization procedures). The interactions occurring at contact interfaces control the friction and wear behavior of solid surfaces and, ultimately, the overall performance and efficiency of bio-electromechanical components.
E240: The Essentials of Mechanics of Physical Systems-A Primer
As we are entering the golden age of industrial design, simulation, robotics and manufacturing, a deep and crystal-clear understanding of the topics of statics, strength of materials and dynamics is needed more than ever. This primer is a condensed synopsis of statics, strength of materials and dynamics, and is designed to augment (not replace) the large array of courses on the subject. This primer does not contain homework problems. This primer has one simple purpose, to provide the essentials, and is meant as a supplement to the usual courses in this area.

This class builds upon the first class and expands towards diffusion, phase diagrams, phase transformation, solidification, and alloy systems. Examples include steels, aluminum and titanium alloys. Furthermore, composite materials and ceramics are featured for high performance applications.
The final shape of any high precision component is often given by machining processes. Understanding the details about various machining processes is key to generate precise high-quality metal components. While machining is a cutting process this section will also featuring joining processes such as welding and brazing introducing the students to the materials changes associated with these processes. This class ends with state-of-the-art laser machining and which becomes of increasing relevance today.

This class will cover the response of materials to stresses and strains. Basic mechanics coupled with material science will lead the student to understand why and how materials fail. Tensile/compression, fatigue, creep, ageing, dynamic strain ageing and of course linear elastic fracture mechanics are discussed. Students will learn how to judge different failure modes based on fracture surfaces and deformations.
