When two bodies are in contact, various surface/subsurface damage problems may arise,
which significantly shorten the service lives of functional components. These damage …

This paper reviews the state-of-the-art contact force models for non-spherical particles,
which describe the relationship between the contact force and the geometrical, material, and …

Many devices, including touchscreens and robotic hands, involve frictional contacts.
Optimizing these devices requires fine control of the interface's friction law. We lack …

This study develops a new fractal contact model to evaluate contact status on rough
surfaces. Specifically, the three-dimensional Weierstrass-Mandelbrot function is used to …

接触碰撞行为作为大自然与多体系统中的常见现象, 其接触力模型对于多体系统的碰撞行为机理
研究与性能预测至关重要. 静态弹塑性接触模型与考虑能量耗散的连续接触力模型是研究接触 …

The size distribution of contact spot areas is critical for the evaluation of contact behavior of
rough surfaces. A size distribution law proposed by Mandelbrot has been used widely in …

The study of contact mechanics is rapidly expanding in scope and importance. However,
most studies of spherical do not spend significant time comprehensively analysing PEEQ …

The quality of powder beds is a key factor governing the density of bulk parts produced by
the powder bed fusion–additive manufacturing (PBF-AM) process. Conventional …

It has been shown experimentally that boundary friction is proportional to load (commonly
known as Amontons' law) for more than 500 years, and the fact that it holds true over many …

This study investigates the wear and mechanical properties of additively manufactured (AM)
17–4 precipitation hardening (PH) stainless steel (SS) and compares to those of …
