Text Book: DYNAMIC BEHAVIOR OF MATERIALS
Marc Andre Meyers
J. Wiley, 1994
Course Description: The dynamic behavior of materials is relevant in a multitude of situations ranging from automobile crashes to space exploration. The mechanical response of metals, ceramics, polymers, and composites is dependent on the velocity at which they are deformed.
Wave propagation effects, due to material inertia, play an increasingly important role as the velocity of loading is increased. In this class we will learn:
2. Constitutive equations that represent the mechanical behavior of materials at different strain rates and temperatures, and stress states.
3. Applications ranging from material processing methods(welding, compaction, forming) to more esoteric uses.

Grading and Homework
Homework (23 questions), reading assignments, and reports (one, on topic of choice by student) will be assigned on Thursdays and collected on the following Thursday, at the beginning of class.
Solutions to homework will be on soft reserves. Since many homework The exams will be closed book. I wish you good luck and may the course be instructive, formative, challenging, and fun.
a) A brief statement of the problem including any necessary given information or
assumptions you decide to make.
b) Figures
c) Mathematical analysis
d) Your final answer with a BOX drawn around it. This is essential!
Do not carry around symbols for units as you walk through a problem. When you give a
final answer, then is the time and place to attach units. Use the abbreviations in the text for
Mega Pascal (MPa), density (g/cm³), etc. Don't forget correct units.
