“…Contact interfaces involving rough surfaces can be modeled by using semi-analytical methods (SAMs) built on core analytical solutions and supported by efficient numerical approaches, including the conjugate gradient method (CGM) [40] and the fast Fourier transform (FFT) method [41,42]. SAMs have been used for solving numerous contact problems, such as magnetoelectroelastic contacts [43][44][45], elastoplastic contacts [46][47][48][49], and contact involving rough surfaces [50][51][52][53]. Derivation of the core analytical solutions, in terms of displacements and stresses, is essential for developing a contact model and simulating the surface interactions in such structures.…”

Lithium metal anodes are critical enablers for high energy density next generation batteries, but they suffer from poor morphology control and parasitic reactions. Recent experiments have shown that an external packing force on Li metal batteries with liquid electrolytes extends their lifetimes by inhibiting the growth of dendritic structures during Li deposition. However, the mechanisms by which pressure affects dendrite formation and growth have not been fully elucidated. For

“…However, in many engineering applications, the fretting mode is not tangential and the contact configuration is also not ball-on-flat. For example, fretting between the hub and the blade carrier in a controllable pitch propeller, and fretting between the bogie and the railcar body on a train are all typical torsional fretting under flat-on-flat contact [17][18][19]. Both the fretting modes and contact form have a great influence on the fretting wear behavior.…”

Influence of surface topography on torsional fretting under flat-on-flat contact were investigated. Contact surfaces of the lower specimens were prepared by milling with different initial surface roughness while the upper specimens were polished. Results indicate that with the increase of surface roughness, friction torque and accumulated dissipated energy present a first increase and then decrease tendency and are higher when the texture is perpendicular to the relative movement direction. The wear volume and wear rate present increasing and decreasing tendencies separately for textures parallel and perpendicular to the relative movement direction, and they are higher when the texture is parallel to the relative movement direction. The results can provide guidance for the initial surface design to reduce fretting wear.

Fretting wear is a major form of fretting damage involving various factors, such as material properties, surface roughness, surface topography, lubrication conditions, environment temperature, type of loading, and loading phase difference. In this study, ABAQUS is used to establish three models to simulate the variation of wear depth with the amplitude of additional load. The influence of the phase difference between additional load and original load is considered. Four phase difference angles are involved, i.e. 0°, 90°, 180°, and 270°. Results indicate that the rule of the variation of wear depth with the additional load amplitude increasing varies under different phase differences. It is observed that for the 0° phase difference, the wear depth firstly decreases then increases with the increase of the additional load. However, the wear depth increases monotonously in the case of the 180° phase difference. The variation of wear depth with additional load amplitude for 90° phase difference is similar to that of the 270° phase difference. The depth of wear is firstly kept at a relatively low level and then increases sharply, with the increase of the additional load. It is found that the distribution of shear stress and relative slip at the contact interface is also affected by the phase difference.
