That is an intersting idea! I had been thinking about clamping the end of
a piece of tissue and pulling it around an arc and measuring the angle at
which the break occurs. Your approach could be simpler. Will have to
think about it a bit, and maybe even try it.
The other idea I had was to measure the force required to pull the tissue
around the arc. With the combined values of force and deflection we might
also be able to get at the internal stress in the tissue. Of course the
trick is how to make this easy to do, and simple to build.
