“…To keep consistent with the theoretical model material, 39 and we also referred to other literatures, 14,23,24,[39][40][41][42] isotropic hardening material was selected for the simulation model material The schematic diagram of the isotropic hardening bilinear elastoplastic model is shown in Figure 5. In this paper, the steel shot was selected, and 18CrNiMo7-6 was selected as the target material.…”

In this paper, the theoretical models of the surface topography and residual stress (RS) were proposed, and the abrasive water jet sequential peening (AWJSP) finite element models were established by using ABAQUS. Then, the formation mechanism of the surface topography in multiple passes AWJSP process and the coupling mechanism of RS in a single and multiple passes AWJSP process were analyzed. After that, the influence of the number of shots (i.e. N), the distance between the center of adjacent shots Dc, shot velocity v, and shot radius R on the surface topography and residual stress field (RSF) of the target were investigated. Results show that successive dimples were formed by single-pass AWJSP, the RSF formed by the impact of each shot will influence the previous RSF, and that will be coupled with it. In multiple passes AWJSP process, decreasing Dc can decrease the surface roughness, the surface smoothness of the target material will gradually become better, and the RSF will also be uniform. Under full coverage condition, the surface roughness Rt and mean width of the profile Rsm will gradually decrease with the decrease of Dc, while the change of Dc has little influence on the RSF. Increasing the v can increase Rt and Rsm, and it is beneficial to induce a large and deep compressive RS layer. Increasing the R can decrease Rt, Rsm remains unchanged, and it is beneficial to induce a deep compressive RS layer.

“…Similarly, deep rolling introduces a compressive treatment on the surface, and in the literature fatigue improvement particularly concerns the low plasticity burnishing with the ball type indenter; for example the paper by Prevéy and Cammett on 7075-T6 alloy [51]. Fretting fatigue improvement with shot peened and deep rolling was reported by Majzoobi et al [52][53][54] where a dedicated equipment was used for the rolling of the specimens. Santus et al [55] recently investigated a conical indenter that can be used both on milling and turning machines, and the parametric dependences of the residual stress distributions were experimentally obtained.…”

“…2. Some of them directly modeled the spring using spring or beam elements (Giner,et al (16); H-Gangaraj, et al (17)); others attached a plate with low modulus of elasticity to the side of the fretting pad to act as a spring (Iyer and Mall (4); Madge, et al (18); Farris (19)). Without this spring, the fretting pads always move with the specimen when it is subjected to axial stress because a stick zone exists.…”

Fretting fatigue is a combination of two complex mechanical phenomena, namely, fretting and fatigue. Fretting appears between components that are subjected to small relative oscillatory motion. Once these components undergo cyclic fatigue load at the same time, fretting fatigue occurs. Fretting fatigue is an important issue in aerospace structural design. Many studies have investigated fretting fatigue behavior; however, the majority have assumed elastic deformation and very few have considered the effect of plasticity. The main goal of this study is to monitor the effect of different fretting fatigue primary variables on localized plasticity in an aluminum alloy (Al 2024-T3) test specimen. In order to extract the stress distribution at the contact interface under elasto-plastic conditions, a modified finite element contact model was used. The contact model was verified through comparison with an elastic analytical solution. Then, a bilinear elasto-plastic isotropic hardening model with a von Mises yield surface was implemented to simulate the material behavior of the aluminum alloy. The effect of different fretting fatigue primary variables, such as axial stress, contact geometry, and coefficient of friction, on localized plasticity was investigated. Finally, the relationship between the location of maximum localized plasticity and Ruiz fretting damage parameter with the crack initiation site is discussed.
