"On the basis of fatigue tests of nodular cast iron at symmetric push-pull loading and at repeating loading in tension the Haigh and Smith diagrams are constructed, which very clearly express the influence of loading cycle asymmetry on fatigue behaviour. It turns out that irons are much more sensitive to mean stress of loading cycle than structural steels. The dependence of stress amplitude on mean stress is not linear as usually stated for irons but it is more or less convex, described by power law with exponent lower than 1.
