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.
You can download it from inkscape’s website and to install it there’s .config directory on your home directory with an inkscape folder where you can put in extensions, templates, etc. Restart inkscape
after dropping the files there.
