“…Namely, the influence of the grid density on the contact stress is insignificant as it is less than 8 μm. Therefore, a mesh size of 8 μm × 8 μm was used in modelling, which is consistent with Shi's model . To facilitate the stress extraction, a local coordinate system was created at the contact centre O´, as illustrated in Figure B.…”

“…In particular, the critical plane approach has gained the widest application. Various models have been developed on the basis of the maximum stress, strain, and strain‐energy density at a critical plane . Recently, Li et al proposed a fretting related parameter based on fretting fatigue mechanism.…”

“…They introduced the fretting related parameter into the strain‐based critical plane model of Kanazawa‐Brown‐Miller and found a good consistency with experimental result. Shi bridged the plain multiaxial fatigue and fretting fatigue through introducing stress gradient into the Smith‐Watson‐Topper (SWT) model. However, the prediction is dependent on specific multiaxial conditions and multiaxial fatigue models used.…”

The present study investigated the fretting fatigue crack initiation of dovetail structure based on experimental observation and multiple axial criteria. Two typical critical plane approaches of the Smith‐Watson‐Topper (SWT) and the Fatemi and Socie (FS) model were used to predict the crack initiation location, orientation angle, and fatigue life. The results indicate that both SWT and FS models predict consistent results with the experiment in crack initiation location. Regarding the crack initiation angle, FS model shows good agreement with the experimental observation, but SWT model exhibits a large difference. The two models give conservative results in fretting fatigue life. In view of this, the theory of critical distance (TCD) was incorporated into the SWT and the FS models. It shows that both the TCD‐SWT and the TCD‐FS predict fatigue lives within a scatter band of 2. It suggests that introducing the TCD into the critical plane model can greatly reduce the conservatism of the prediction. Furthermore, the prediction has less dependence on specific models.

The fretting wear behaviours of 304 stainless steel at different displacement amplitudes were investigated by using a SRV‐IV fretting tester in air and sea water, respectively. In air, the friction coefficient as well as the fretting damage of 304 stainless steel increased with the increase of displacement amplitude, and the fretting regime changed from partial slip regime to gross slip regime. Correspondingly, the wear mechanisms transformed from local fatigue and slight oxidation to the combination damages of adhesion wear, abrasive wear, and oxidation. Compared with the dry friction conditions, sea water had a strong effect on fretting behaviour of 304 stainless steel. Adhesion wear was effectively suppressed due to the cooling and lubrication effect of sea water. Therefore, friction coefficient and wear depth decreased significantly. And the damages of 304 stainless steel in sea water were mainly caused by abrasive wear, slight adhesion wear, and corrosion wear.

Lightweight metals and metal alloys provide the opportunity to fulfill the exigent weight‐saving requirements for structural components. Mechanical surface treatments, in particular, shot peening and other varieties of impact‐based surface treatments are found to be able to significantly promote the structural application of lightweight metals through enhancing their mechanical performance. Moreover, these treatments have substantiated a notable prospect to modulate the surface–environment interaction of the treated material, bringing in original functionalities in multiple fields of application. Herein, the current state‐of‐the‐art in the implementation of shot peening‐based surface treatments is reviewed regarding lightweight metallic materials. The recent advancements are described focusing on the foremost characteristics of the major lightweight metals commonly used in aerospace, automotive, and biomedical sectors. Emergent applications and the existing challenges are highlighted. Lastly, future perspectives on tailoring the effects of shot peening‐based mechanical surface treatments to boost the appeal of lightweight metals as structural components are provided.
