I’m almost positive this could be improved, but here’s a bare bones starting point for any interested parties. Eight samples, using the inkscape Render > living hinge on a 1x1.5" rectangle. Takes 6"x 6" for the whole test. I’ve never done anything with living hinges and I was never any good at physics so the scatter-shot approach worked great for me. File might be useful one completely unfamiliar materials to get you headed in the right direction. The image is just a screenshot, make sure you download the zipped file.
