MS 360[Mechanics of Materials ]
   
Instructors Prof. Do Kyung Kim , phone 350-4118, room 3307, email dkkim@kaist.ac.kr 
Student consultation appointments arranged by email, but feel free to drop by anytime.
 
Subject Goals
  1. Develop the formal theory of solid mechanics - the equilibrium and constitutive equations.
  2. Develop closed-form and computational methods for stress analysis of typical engineering structures.
  3. Introduce the atomistic mechanisms underlying mechanical behavior of materials, in the context of process - structure - property - performance concepts in materials engineering.
  4. Provide continuing development in mathematics and computer operations for engineering problems.
  5. Provide a context for mechanics of materials within the broad practice of modern engineering, to include statistical approaches, design methods, case studies, and the societal responsibility of engineers.

Grading / align="left">Individual homework, quiz problems, and team project will be graded on a 0-5 scale, and averaged for the problem set or quiz overall grade. The two quizzes, the problem set, and team project average count equally toward the final grade (each 25%)
 
4.8 ~ 5.00 A+
4.6 ~ 4.79 A
4.4 ~ 4.59 A-
4.2 ~ 4.39 B+
4.0 ~ 4.19 B 
3.8 ~ 3.99 B-
3.6 ~ 3.79 C+
3.3 ~ 3.59 C
3.0 ~ 3.29 C-
2.0 ~ 2.99 D
 
     
Quizzes / The two quizzes will be given during the regular mid and final examination periods on Oct. 20 and Dec. 15 (one and half hour exam). Quizzes missed due to documented medical problems and other (very) exceptional circumstances will be made up by oral examination on an individual basis. Quizzes are closed-book, although a single sheet of notes will be allowed. 
Quizzes may include both analytical problems similar to those in the homework assignments, and also questions dealing with concepts discussed in class or included in the reading assignments. Keeping up with the reading and associated problems on a daily basis, and insuring that the various concepts are well understood, is certainly recommended.
     
Homework / Problem sets will normally be submitted not later than one week after posting of problem. Occasional submissions up to a few days late will usually be accepted without penalty (subject to honesty considerations described below), although of course tardinesss should be avoided if possible.
       
Computer Usage / Modern engineering practice in Mechanics of Materials is highly computer-oriented, and you are encouraged to use MS460 as a means of furthering your computer expertise. Usually, you'll be free to choose what software seems best to you (including none at all).
       
Team Project / Team project is planned to encourage using computer to solve some problems. Installation and usage of FEit(basic Finite Element Method package) in our new SUN workstation or the other PC-based computer is the primary task. Educational program for Mohr circle construction on Web environment may be another task. The other task highly computer-oriented task would be possible.
     
Academic Honesty / All work turned in for credit - problem sets, quiz papers, etc. - must be your own individual work unless specific instructions to the contrary have been given to you by the instructors. 
Group discussion of problem sets is allowed and encouraged, but the problems should then be worked out and written up on an individual basis. Turning in problems copied directly from bibles is cheating, and you are encouraged to contact the instructors for help if you get stuck on a problem.
