Supplementary Texts

Malvern, L. E. Introduction to the Mechanics of a Continuous Medium. Paramus, NJ: Prentice Hall, 1977. ISBN: 0134876032.

Assignments and Exams

Problem sets will be given out approximately weekly. We will also discuss papers from journals. There will be a take-home final exam.

Grading

Grades will be based 2/3 on the homework, 1/3 on the final.

Collaboration

You are encouraged to discuss problem sets to help each other on approaches, etc. But do not copy answers - work them out yourself. Do not discuss the exam.
