WebBending stresses in curved beams do not follow the same linear variation as straight beams, because of the variation in arc length. Even though the same assumptions are used for both types, i.e. that plane section perpendicular to the axis of the beam remain plane after bending and that stress is quite different. all gold dutchWebJan 31, 2024 · The stress comparison also emphasizes that straight beam theory predicts nonconservative results for highly curved beams. In this case, the maximum stress is underestimated by around 40 percent!
