it does though! even for very thin objects like a sheet of paper, bending anything will stretch/squish material depending on whether it’s on the inside or outside of the bend. that’s why paper becomes creased when it’s folded!

an easy way to think about it is with tubes. the inside circumference is always smaller than the outside because when you introduce a curve you’re either lengthening the outside, shortening the inside, or both.
