A 1040 steel has been heat-treated to a yield stress of 900 MPa and a tensile yield strength of 1330 MPa. The endurance limit (at 106 cycles for cyclical loading about a zero mean stress) is quoted as 620 MPa. Your Table 11.1.

S-N curve for a SAE 4140 steel. company is considering using this steel with the same heat treatment for an application in which fatigue may occur during cyclic loading with R = 0. Your boss is considering shot peening the steel to induce residual compressive stresses in the surface. Can the endurance limit be raised this way? If so, by how much? Discuss this problem with reference to the Goodman diagram using any relevant calculations. Stress, MPa
