Required information
A solid round bar with a diameter of 2.97 in has a groove cut to a diameter of 2.676 in, with a radius of 0.15 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. Determine the factor of safety for fatigue based on infinite life using the modified Goodman criterion and the factor of safety for yielding.
Determine the endurance limit for this material as well as the value after correction for surface finish, sizing, and loading.
The endurance limit for the material is kpsi.
The endurance limit for the material after correction is kpsi.
