“…The problem of subsurface crack initiation has often been investigated using the different multiaxial highcycle fatigue hypotheses [6,7,9,11,14,17,26,33]. These criteria are based on different approaches (see Sec.…”

“…Such a problem is very important for parts made of hard materials in which constant a DV achieve larger values. Because of this, the DV model has recently been criticized [11,17,[26][27][28]. One of the proposed modifications of the DV's criterion is to neglect the hydrostatic stress influence by adopting coefficient a DV = 0 for negative values of σ H ( Fig.…”

“…The subsurface cracks are the most dangerous form of fatigue failure. Such problem (subsurface fatigue) is often investigated by applying MHCF hypotheses such as proposed by Crossland [11][12][13], Dang Van, Papadopoulos [11], Liu-Mahadevan [14][15][16], Liu-Zenner (this model requires four fatigue limits) [17]. The Dang Van model has been frequently used in RCF analysis of railway wheels and rails [5,[18][19][20][21][22], rolling bearings [23,24] and other mechanical parts working in RCF loading condition [25].…”

The application of multiaxial high-cycle fatigue criteria to the analysis of the subsurface rolling contact fatigue of structures working in contact conditions is discussed. In such objects, an increase in compressive and shear stresses is strongly non-proportional. Therefore, the first part of the paper is devoted to the comparison of the results of six recently used high-cycle fatigue criteria estimating the effort for both different multiaxial proportional and non-proportional loads. In the second part of the paper, the issue of frictionless and tractive rolling contact fatigue is discussed. The fatigue load capacity of a crane wheel has been estimated using recently popular criteria. The orientation of critical planes and location of dangerous points are determined and discussed in detail. It has been found that the Dang Van criterion, which is often proposed in rolling contact fatigue analysis, underestimates the equivalent fatigue stress for such type of loads. Comparison of the results obtained using different multiaxial criteria with the results of the experimental tests enables a selection of criteria suitable for fatigue assessment of machine parts working in cycling rolling contact conditions.

“…Jabbour et al (2015), Fedorko et al (2016) put forward a method which can be used to calculate the distribution of the stress at the tooth root and of the contact stress along each contact line of helical gear. Conrado et al (2011) applied the Dang-Van and the Liu-Zenner multiaxial fatigue criteria to judge the contact fatigue limit. And the relationship between the generated temperature and the contact fatigue limit was received.…”
