“…However, the surface roughness becomes more sensitive to the static load as larger deformations are produced. The nature of the force load between the strike pin and target material has been studied by several researchers [23,39], who found that the dynamic impact force can be expressed as a typical wave. This wave can be described with the following equation:…”

“…In a series of studies by Umemoto [57][58][59], it was found that the key condition for obtaining nano-sized grains is an effective plastic strain is close to 8. Using simulation models, many studies have estimated grain refinement level and found that the effective plastic strain is a practical method for predicting grain refinement results [35,39].…”

“…Achintha [30,46] developed a hybrid explicit finite element-eigenstrain model to investigate the parameters of LSP and found that the study's simulated results corresponded well with its experimental results. Other process parameters and results such as shot peening coverage [42], surface roughness [37], residual stress [30,34,38,39,52], and process angle [49] have been successfully simulated and studied. The simulation of S 2 PD to produce surface nano-crystallization was investigated by Bagherifard et al [53], while other studies found that element size is sensitive parameter in the simulation results [35].…”

Research on influences of contact force in chemical mechanical polishing (CMP) process

A series of simulations of chemical mechanical polishing (CMP) were conducted to investigate the contact force between abrasive particles and specimens by using the finite element method (FEM). In this paper, a micro-contact model, which only involves the mechanical interactions, was set up to simulate the polishing process by changing the processing parameters, including the downward pressure, abrasive size, and polishing speed. Simulation results show that the contact force becomes larger when the downward pressure increases. In addition, when the downward pressure and abrasive size increase, the fluctuation of the contact force becomes large, whereas it declines with decreases in the polishing speed. In addition, corresponding CMP experiments were done to investigate the material removal rate (MRR) and polished average roughness (Ra) under different simulation conditions. Through the establishment of the contact force properties in the simulation and the MRR and Ra in the CMP experiment, qualitative research has been done on the relationship between the contact force in the simulation and experimental results. Experimental results indicate that the MRR and surface roughness are influenced by the contact force. A high MRR can be obtained by a large contact force and dramatic fluctuations can lead to poor surface-finish quality. The investigation contributes to obtaining higher polishing efficiency and lower surface roughness through optimization of the polishing parameters.

Metals and their alloys have found extensive applications in numerous fields. Various surface modification techniques have received significant attention for their potential to improve the adaptability of materials to complex environments. One such technique, the ultrasonic surface rolling process (USRP), introduces a deformation layer by applying static stress and dynamic impacts to the surface of metallic materials. During USRP treatment, remarkable beneficial compressive residual stresses (CRS) and hardened layers are induced and, simultaneously, the surface finish of the material is improved. These modifications not only effectively suppress the initiation and propagation of fatigue cracks but also significantly enhance the mechanical properties, wear, and corrosion resistance of the materials, thereby greatly prolonging the service life of structural components. The review starts with the mechanisms of USRP, discussing grain refinement, control of surface roughness, and the introduction of beneficial CRS. Subsequent sections provide a comprehensive analysis of how these modifications impact material properties, encompassing hardness, plasticity, fatigue, wear, and corrosion resistance. Furthermore, it introduces the latest advancements in USRP technology, including thermal/electric pulse‐assisted USRP, its integration with other surface treatment methods, and its applications and prospects across various fields.
