Fatigue results from cyclic or alternating loading with the fracture developing as a result of crack initiation and growth. For a crack to propagate, it is necessary for the crack to open and for the stresses at the crack tip to exceed the tensile stress of the material. If the tensile stresses at the crack tip are not present or are below a critical value, the crack will not propagate. Cast iron was tested under fatigue loading where the stresses were mainly in the compressive region. The lack of tensile stresses increased the range and combination of loading necessary to induced fatigue failure. A Goodman diagram for design purposes were developed. This diagram can be generated from data obtained form simple tension, compression, and rotating-beam fatigue tests. The results of these tests actually indicate a significantly larger region for safe design recommendations.
