Mechanical engineers, Civil Engineers and Bioengineers typically utilize metals, ceramics, plastics, and modern composites.  Electrical Engineers and Engineering Physicists typically work with devices made from semiconducting materials, but  they also utilize optical and magnetic materials among others.  The science and engineering of materials is truly an interdisciplinary field requiring an understanding of solid state physics as well as chemistry.  This is due to the fact that the behavior of materials in an engineering application can be directly related to mechanisms which occur at macroscopic, microscopic, and nanoscopic levels.  Research and design engineers must have an understanding of these mechanisms to determine if the materials of choice are able to function properly.  Furthermore, construction and manufacturing engineers must understand these mechanisms to utilize appropriate fabrication techniques.</div> <bR> <div> <I><B>Classes of Materials, Atomic Bonding, and Basic Structure-Property Relationship</B></I><I><B>s</B></I></div> <div> During the first week of this course you will be introduced to four basic classes of materials: metals, ceramics & glasses, polymers, and composites.  Semiconductors will also be discussed.  Topics in General Chemistry will be reviewed, and atomic bonding will be discussed.</div> <bR> <div> <I><B>Macroscopic Characteristics and Material Properties</B></I></div> <div> Next, properties and characteristics of materials will be discussed at the macroscopic level.  You will be introduced to mechanical properties of materials including tensile strength, hardness, impact resistance, fracture toughness, and fatigue resistance.  In addition, thermal properties and viscoelasticity will be discussed, and special consideration will be given to composite materials including wood and concrete.</div> <bR> <div> <I><B>Microscopic Characteristics and Structure-Property Relationships</B></I></div> <div> Microscopic characteristics of materials will be discussed in the third part of the course.  This includes a study of crystalline structures and the role of defects, impurities, and dislocations in determining material behavior.  Other topics include diffusion, phase diagrams, kinetics, precipitation hardening, hardenability, and heat treatment.  Structure-property relationships for metals, ceramics, glasses, polymers, and elastomers will also be discussed.</div> <bR> <div> <I><B>Corrosion and Failure Analysis</B></I></div> <div> Corrosion and failure mechanisms for materials will be presented in this last section of this course.  Specific topics include galvanic corrosion, sensitization, concentration cells, cavitation, and wear. </div> <bR> <div> <B><U>Lecture/Recitation Periods</U></B><FONT SIZE="3" COLOR="#111111" FACE="Times New Roman" > (see link below for the Engr 45 calendar and syllabus)</FONT></div> <bR> <div> Monday, Wednesday, Friday 3:30 - 4:50 PM, Anderson 216.  </div> <bR> <div> <B><U>Laboratory Periods</U></B><B> </B><FONT SIZE="3" COLOR="#111111" FACE="Times New Roman" >(see link below for general information about the Engr 45 laboratory)</FONT></div> <bR> <div> Section 1 – Tuesday 3:00 - 5:50 P.M. – Baun 110.</div> <div> Section 2 – Thursday 3:00 - 5:50 P.M. – Baun 110.</div> <bR> <div> <I><B>Click on the links below  to read the documents within your web browser, or right-click on the document and select "save as" to download the document to your computer.

Reading assignments are shown in the syllabus, and handouts will be provided to supplement the textbook.  Written homework problems will typically be assigned every class period, and they will be due at the start of the next class period (3:30 P.M.).  Late homework will not be accepted under any circumstances.
