    Subject Goals 

    - Develop the formal theory of solid mechanics - the equilibrium and constitutive equations.
    - Develop closed-form and computational methods for stress analysis of typical engineering structures.
    - Introduce the atomistic mechanisms underlying mechanical behavior of materials, in the context of process - structure - property - performance concepts in materials engineering.
    - Provide continuing development in mathematics and computer operations for engineering problems.
    - Introduce the latest developments in the fields of nanomechanics, which will be relevant in mineralized biological tissue, bone and teeth.

    Grading

    Individual homework, two exams, and two team projects will be graded on a 0-5 scale. The two exams, the home work problem sets, and two team projects average count equally toward the final grade (each 1/3)


    Exam

    The two exams will be given during the regular mid and final examination periods in October and December (one and half hour exam). Exams 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 MS360 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

    Two team projects are planned to encourage using computer to solve some problems.  Installation and usage of winFElt (basic Finite Element Method package for Windows) and FRANC2D is the primary task.  More sophisticated Finite Element analysis program to solve more complex problem is next task. Educational program for Mohr circle construction on Web environment (or standalone executable) may be another task.  The other task highly computer-oriented one would be possible for team project subject.
    Experimental challenge to understand the mechanics of materials is another set of team project. Visualization of stress contour by photoelasticity and measurement of time-dependent crack growth behavior, construction of stress measuring by sensor (load cell) would be some of examples.
    Data acquisition and analysis for micro and/or nano indentation would be new set of team project examples
