... not occur under similar conditions in any number of cycles. Because this particular ductile iron has a tensile strength of 454 MPa (65.8 ksi), its endurance ratio is 0.41. The effect of stress raisers on the endurance limit has been evaluated by the use of notched test bars. For this purpose, a notch...
