WEIGHTING: 20% homework, 50% tests, 30% final exam. As judged appropriate in individual cases, these weights may be altered to the student's benefit where substantial improvement is realized near the end of the course, homework missed due to major illness, etc.

TESTS:There will be three tests. Absence during a test will result in a grade of zero. Makeup tests will be given only for a document illness or death in the immediate family.

TEST PAPERS: Please leave flat and staple upper leftcorner. Please write on only one side of the page with PENCIL ONLY. Upto 10% may be deducted for failure to follow these instructions.

HOMEWORK: Homework problems are due the next class period after the class period they are assigned: e.g. assingments given on Tuesday are due Thursday and assignments given on Thursday are due Tuesday. Assignments will be given every Tuesday and Thursday in class except the class period before tests are typically reserved for review. All homework will be submitted on 8-1/2" x 11" light green engineering paper. Poorly written homework will not be graded. All pages will be stapled togther in the upper left corner. Your LAST NAME FIRST should appear in the top left corner, SSN No. in the top center, and the Assignment No. and problem numbers in the top right corner. All homework will be written ONLY IN PENCIL and ONLY RED INK PEN must be used when reviewing homework in class. When homework problems require the use of your PC, include a printed copy of your computer program. No homework will be accepted late FOR ANY REASON. If you fail to hand in more than one assignment due to major illness or family emergency, please provide a note of explanation and attach any available supporting documentation and your homework will checked for accuracy and correctness but not graded. Each assignment will be given a grade based on equal weight for each problem in the assignment: for example if there are 5 problems each problem will be assigned 10 points for a total possible grade of 50 points total. Final homework percentage is simply calculated by adding your total points and dividing by the total possible points.

HONOR CODE: The Virginia Tech Honor code applies to all homework and exams, and no form of dishonesty will be tolerated by the instructor or the students. If a serious attempt to work a homework problem is unsuccessful, then help may be sought from another student, including those currently in the course. But this help must be limited to the minimum necessary to allow further progress. Copying of another students work, including work from old notes, or permitting your work to be copied, is considered a serious breach of the honor code. In our class we review the problems on the day they are due before the lecture begins. Correcting or copying your homework with pencil during the review in class is a honor code violation.

EDUCATIONAL OBJECTIVES:

Upon successful completion of this course, the student will be able to:

1. identify the major classes of engineering materials and relate their macroscopic performance to the microscopic properties characteristic to each class

2. perform fundamental calculations and analyses necessary to describe the mechanical behavior of materials

3. identify and recommend processing methods by which specific material structures can be produced and their properties developed or enhanced

4. correctly identify and select appropriate materials for a given application based upon fundamental relationships between microscopic material structure and properties, including their known ranges of applicability and limitations.
