"Mode II and mode III fatigue crack growth rates and the related intrinsic stress intensity factor range thresholds deltaKIIeff,th and deltaKIIIeff,th were for a long time expected to be equal. However, there are many theoretical and experimental indications of a slower crack growth rate and a higher threshold for mode III than that for mode II for various metallic materials. In this article, a description of shear-mode fatigue crack growth for specimens made of ARMCO iron in terms of a diagram da/dN vs. deltaJ is presented and compared with that based on deltaK. For higher applied loads the description in terms of deltaK is no more valid which turned out from a precise assessment of plastic zone size for a wide range of shear-mode loading levels in these specimens. This numerical elasto-plastic analysis revealed that the small-scale yielding conditions were only fulfilled in the near-threshold region and, for higher loading levels, the deltaJ approach should be utilized.
