Question

A wide sheet (1 mm thick) of steel is bent elastically to a constant radius of curvature, p 500 mm measured form the axis of bending to the center of the sheet as shown in figure 1. Find the stress in the surface. Assume that there is no net force in the plane of the sheet. Knowing that E 208 GPa, and v 0.3 for steel. 04) a) Figure1
