How does a folding phone's glass screen bend without breaking?
Change the fold radius, glass thickness and whether the layers are glued or sliding, and watch the glass strain cross the break line.

About this project
Lets you change fold radius, glass thickness and whether the layers are glued or sliding, and shows outer-surface strain. The index text estimates that 0.5 mm phone glass folded tightly to 2 mm would stretch about 12% and shatter, while 30-micron glass stays under 1%, and notes that sliding layers bend far more easily than one glued slab.
