“…Moreover, the majority of fatigue predictive methods take into account the initial measured residual stress values and neglect their evolution under cyclic loading. This assumption is controversial by published data related to stabilized residual stress profiles showing relaxation and redistribution phenomena [2, 8,12,13]. Moreover, it has been reported that the most fraction of residual stress relaxation is monotonic, since it occurs at first cycles.…”

The effects of machined and treated surface characteristics on the fatigue strength were analyzed on the basis of experimental results related to AISI D2 ground surface and AA 5083-H111 hammered surface. The fatigue strength improvement resulting from controlled grinding and mechanical surface treatment was discussed on the basis of the beneficial effect of the work hardening and the stabilized residual stress. A numerical procedure using F.E.M for calculating residual stress and work hardening evolution under cyclic loading has been developed. The validation of the numerical procedure was carried out by comparing the calculated residual stress profiles to those resulted from XRD measurements. The multi-axial criterion accounting for the work hardening and the residual stress was used to predict the fatigue life of notched samples. IntroductionIt is well established that residual stress and work hardening, generated by machining and surface treatment processes, influence the fatigue life of mechanical parts [1][2][3]. That is why they are often considered in fatigue strength predictive models using multi-axial fatigue criteria [3] and fatigue life assessment by local strain-life approaches [4,5]. Experimental and modeling results confirm the detrimental effect of tensile residual stress which is considered to promote fatigue crack nucleation and to accelerate their propagation [6]. In contrary, it has been demonstrated that the compressive residual stress, generated by controlled machining processes and surface treatments, improves the fatigue strength by delaying the crack nucleation and by reducing the crack propagation rate [2,7,8]. However, most of published data related to fatigue crack nucleation and growth involving residual stress were discussed on the basis of their initial distribution [9][10][11]. Moreover, the majority of fatigue predictive methods take into account the initial measured residual stress values and neglect their evolution under cyclic loading. This assumption is controversial by published data related to stabilized residual stress profiles showing relaxation and redistribution phenomena [2,8,12,13]. Moreover, it has been reported that the most fraction of residual stress relaxation is monotonic, since it occurs at first cycles. Relaxation could progress under cyclic loading if the plastic misfit itself continues to change until stability [13][14][15]. Since the stabilized residual stress state is an important parameter for fatigue life prediction, it is of paramount importance to determine, in this study, the parameters that govern their evolution during cyclic loading. These parameters will be taken into account by the developed numerical procedure to calculate stabilized residual stresses and therefore fatigue life time. Analysis of the residual stress cyclic stability is based on the experimental results of surface characterization and fatigue tests conducted on AISI D2 ground surface and AA 5083-H111 machined and wire brush hammered surfaces.

“…It is well known that the machining surface integrity influences strongly the fatigue lifetime of materials, since fatigue micro-cracks initiate always at the surface [12][13][14][15][16][17]. For this reason, several studies have been dedicated to the effects of milling on fatigue behaviour of many materials, particularly aluminium and titanium alloys, and superalloys widely used to manufacture structural parts for aviation and aerospace industries [18][19][20][21][22][23][24][25].…”

“…So, it is necessary to ovoid tensile residual stresses occurring during the machining process. However, when the cyclic loading produces plastic deformation, the effect of residual stress will be reduced or disappeared [15,27]. In view of the high-speed milling process of Ti-10V-2Fe-3Al, Yao et al [28] found that the fatigue life of the workpiece is more sensitive to residual stress than to surface roughness.…”

The experimental investigations showed an important difference between integrity of both milled surfaces. The down-milled surface is lowly work-hardened and well finished (lower roughness), but subjected to tensile residual stresses and severely damaged by folds of metal and short micro-cracks. The up-milled surface is highly work-hardened and subjected to compressive residual stresses, but poorly finished (higher roughness) and damaged by a density of micro-cavities due to carbide extraction. The results of 3-point bending fatigue tests revealed that the fatigue limit at 2 × 10 6 cycles of the up-milled state is largely higher of about 26% in comparison with the down-milled state. The effects of surface integrity induced by each milling mode on fatigue strength were evaluated using a HCF behaviour predictive approach based on Dang Van's multiaxial criterion. The predictive results estimated that the pre-existing micro-cracks play a dominant role in the fatigue strength degradation of the down-milled surface while the other surface effects seem to be lower. On the contrary, the fatigue strength of the up-milled surface is less affected by the pre-existing micro-cavities. The detrimental roughness effect (stress concentration effect) is significantly reduced by the beneficial effects of superficial hardening and compressive residual stresses. So, this study revealed that up-milling is the more appropriate mode for a better surface integrity towards fatigue strength of X160CrMoV12 steel than the down-milling mode.

“…Residual stress is one of the most important factors in assessing the surface integrity of a ground component [18,19] because improper distributions of residual stresses will remarkably influence the service life and reliability of the component [20][21][22]. For this reason, characterization and prediction of grinding-induced residual stresses have been vital to the advanced design and fatigue failure analysis of components for aerospace, aviation, and automotive applications [23].…”

This paper provides a state-of-the-art review on the investigations into the residual stresses in metallic structural materials generated by grinding. The materials covered include steels, titanium alloys, and nickel-based superalloys. The formation mechanisms of the residual stresses and their impacts are specifically discussed. Some major influential factors on the residual stresses formation in grinding, such as grinding wheel characteristics, dressing techniques, grinding parameters, cooling conditions, and properties of workpiece materials, are analyzed in detail. These include experimental measurement, modeling, simulation, knowledge-based monitoring, and fuzzy analysis. Finally, the paper highlights some important aspects of grinding-induced residual stresses for further investigation.
