This program simply displays a square box and progressively deforms
it according to parameters specified by the user (pure shear, simple
shear, and number of steps). The finite strain ellipse, finite strain axes,
and stress axes (assuming a viscous medium) are displayed at each
step of the deformation.

To start a deformation, click the "New Deformation" button and input
your desired parameters. The program will display an undeformed box.
Left-click anywhere in the window to take the deformation forward one step,
and right-click (or ctrl-click) anywhere in the window to take the deformation
backward one step. At any time, you can click "New Deformation" again
to start over.

Stress v. Strain should run on any computer with Java 1.4.2 or later
installed, but the author makes no guarantees. Furthermore, the author
is not responsible for any damage or loss of data caused by running
Stress v. Strain (though the odds of anything untoward happening are
quite miniscule).

Feel free to use Stress v. Strain in a classroom setting and distribute
it to students and colleagues. (They are its intended audience, after all.)
In any other circumstances, do not distribute Stress v. Strain without
The express permission of the author.

VERSION HISTORY
1.0 - Initial Release
1.1 - Added contextual help dialogs, improved error handling to preserve user
input, made minor bugfixes and cosmetic changes (hopefully for the better!)
1.2 - Added background information on the math involved
1.3 - Added the ability to step backwards through the deformation, fixed a few
math bugs, made some positive cosmetic changes
1.4 - When starting a new deformation, Stress v. Strain now retains the input
values from the previous deformation, making repeated simulations easier to perform
1.4.1 - Minor changes to help text
