Stresses: Beams in Bending - MIT OpenCourseWare

We first define a radius of curvature of the deformed beam in pure bending. Because plane cross sections remain plane and perpendicular to the longitudi-nal axes of the beam, the latter deform into arcs of concentric circles. We let the radius of the circle taken up by …

Bend radius - Wikipedia

Bend radius, which is measured to the inside curvature, is the minimum radius one can bend a pipe, tube, sheet, cable or hose without kinking it, damaging it, or shortening its life. The smaller the bend radius, the greater is the material flexibility (as the radius of curvature decreases, the curvature increases). The diagram below illustrates ...
