ME 922 Thermoelasticity and Viscoelasticity
Prerequisite: ME 820 (important), MTH 443 (less important).
Instructor: T. J. Pence, 2452EB, 353-3889, pence@egr.msu.edu.
Time and Place: MW 10:20-11:40
in Room 19 of the Natural Resources Building.
Text: There are two texts from which I will draw lecture
material:
- Mechanical Response of Polymers: An Introduction, A. S. Wineman
& K. R. Rajagopal, Cambridge University Press, 2000.
- Theory of Viscoelasticity: An Introduction, R. M. Christensen,
Academic Press, 1982

Course Description: I will mainly follow the Wineman
and Rajogopal book, which provides a development of viscoelasticity
in genreral (it is not limited to polymers). The order of topics
is anticipated to be as follows:
- Discussion of viscoelastic response
- Mechanical alanogies in one-dimensioanl: Maxwell, Kelvin &
Voight models
- Linear viscoelastic response in one dimension & superposition
principles
- Relaxation and creep, fading memory
- Constant strain rate processes, constant stress rate processes,
recovery,
- Oscillatory processes, complex viscosity
- Three dimensional response, extension/shear coupling
- Axial load, bending and torsion, correspondence principle
- Boundary value problems, correspondence principle for
quasi-static motion
- Thermal effects, time-temperature superposition
- Dynamical effects and wave propagation
- Nonlinear mechanical behavior
Grading: Grades will be assigned on the basis of a few
homework assignments (35%), a mid-term exam (25%) and a project
(40%). The project will involve independent study of a topic of
interest that relates to this course and reporting on that topic
to the class. The final exam time (Friday, May 2,
10:00-12:00) will be used for the last couple project
presentations.
