A solid round bar with a diameter of 2-in has a groove cut to a diameter of 1.8-in, with a radius of 0.1-in. The bar is not rotating. The bar is loaded with a repeated bending load that causes the bending moment at the groove to fluctuate between 0 and 25,000 lbf-in. The bar is hot-rolled AISI 1095, but the groove has been machined.
