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:

  1. Fundamentals of elastic, plastic, and shock-wave propagation.

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 (2-3 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.






  1. All homework assignments will refer to the text unless otherwise stated.  Homework should be neatly written on standard engineering 8 1/2 x 11 paper.  Sloppy or late homework will be penalized or even rejected.


  1. Be sure to show your work on all homework problems; the answer alone is never responsive, and points will be deducted if important steps are missing from your development.  Make liberal use of carefully drawn and labeled diagrams in your homework.  Since significant partial work is usually given some credit on homework, it is a sound strategy to hand in what you can do on each homework problem.  One more thing:  It must be your own work!  Cases of copying will be treated as ACADEMIC DISHONESTY.  You can talk with other students, but you must then do the problem yourself.


  1. Assignments will be announced in class, typically on Tuesday, and will be due the following Tuesday.  Homework is due at the beginning of class on the due date.  Assignments handed in after the beginning of class will be treated as late and will not be graded.  PLEASE DO NOT ATTEMPT TO COMPLETE ASSIGNMENTS DURING THE LECTURE.  THESE WILL NOT BE GRADED.


  1. Each problem should begin on a NEW PAGE and should include the following:

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.


  1. Homework should be presented in a professional manner, meaning neat and legible.  Work handed in with excessive scratch marks and/or arrows will not be graded.


  1. No homework will be accepted late (homework is due in class on due dates before class begins).  A late entrance into the class does not provide an excuse for handing homework in late.


  1. Homework will be returned to you within a week.  Re-grades on homework will be considered for a week after that homework is returned to you.


  1. Please discuss problems concerning grading of homework with your TA before you come to me.  I will only entertain discussion on homework grades after the TA has had an opportunity to discuss your problems with you and has marked out his decision.


  1. Be sure that your name is at the top of the first page of each part.  PRINT your name in block letters, LAST NAME FIRST.  Staple the pages together to ensure full credit.
