Recommended Text: (note this is not required, all required material is covered in class):
Mechanical Behavior of Materials, Marc A. Meyers and Krishan K. Chawla, Prentice-Hall, 1999.

Other resoruces: Other resources consisting of software, web sites and reserve material will Significantly augment the course. This will decrease our reliance on the text

Grading (a one-sided 8.5 x 11" sheet of notes is allowed in exams)
    Midterm I 25%
    Midterm II 25%
    Homework 15%
    Final 35%

Homework will be assigned and due weekly (except for the week with the midterm, and the last week of the course.
