“…In a three-part series of papers, experimental and modeling studies on spall propagation have been carried out recently by Rosado et al [23], Arakere et al [24] and Forster et al [25] where they have identified three stages of spallation. The first stage is surface spall formation.…”

“…The modeling work of [24] was predominantly to study the large magnitude stresses and strains induced by ball impact to the spall edge. The analysis presented here is unique and dynamic in that it simulates a ball impacting a spall edge to determine the relative contributions of residual stress, gradient in yield strength, surface yield strength, and ball density on the extent of damage induced in a spall edge.…”

“…Simulations carried out (not included here) show this. Now, for the cases of a deep groove ball bearing with a raceway Brinell-type of indentation, the spall growth follows what is already described in the literature [15,23,24]. It is to say, the edges of the indentation all around it will create pressure peaks that will drive the spall growth.…”

“…Despite the considerable effort dedicated to study the spall generation and propagation from surface indentations, very little effort is found when it comes to the physical modelling of the spall propagation as a function of the number of overrollings and operating conditions, some important exceptions are [20][21][22]. Spall propagation from indentations has been investigated in detail experimentally and occasionally modelled empirically [23][24][25][26].…”

Propagation of Large Spalls in Rolling Bearings

The paper focuses on studying the propagation of large spalls on the raceways of rolling bearings. This is done by means of experiments and modelling. It is shown that the application of a relatively simple model to describe a spall evolution in time in rolling bearings is feasible. The proposed model is validated using experiments, where rolling bearings with initial pre-damage have been tested and the surface spall progression has been monitored in time. Surprisingly, spall progression in rolling bearings appears to be correctly described by a model of damage initiation. Without the need of a more sophisticated crack propagation model, at least this seems to be the case for a relatively large spall (larger than the Hertzian contact). Where the effects of the pressure build up from lubrication can be ignored. However, dynamic effects cannot be disregarded, since they seem to be the driving force for the propagation direction in some cases. The effect of the shape, size of the initiation point and load sequence is studied as well as the shape of the contact (line or elliptical), giving interesting insights of the propagation mechanisms.

“…Because bearings are widely used, their failure is a topic of great interest. One of the common causes of bearing failure is rolling contact fatigue (RCF) . It is noteworthy to mention that the topic of RCF is not restricted to the bearing field, it is also a topic of great interest in other contact pairs, e.g.…”

Rolling element bearing prognosis is the process of forecasting the remaining operational life, future condition or probability of failure of the bearing. While operational, bearings are subjected to rolling contact fatigue (RCF), and, as a result, a spall is generated on the raceway of the bearing. Complete understanding of the fatigue process is critical for predictive modelling to estimate bearing remaining useful life, which allows improved scheduling of maintenance actions. This work presents an RCF model that was implemented using abaqus finite element software. The RCF model is based on a damage mechanics approach that relates the accumulated microscopic failure mechanisms to a damage state variable and includes representation of material grain structure by a Poisson–Voronoi tessellation. Different microstructures, with a variety of material properties and grain topologies, were constructed for simulation purposes. The geometry of the simulated spalls and the Weibull slopes of the fatigue lives are in good agreement with published theoretical and experimental data. It can be concluded that the assumptions and the simplifications of the current, convenient to use, RCF model yield a sufficiently accurate tool on the basis of previous publications and experimental data.
