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 …

A multi-physics electrical contact model is proposed to study electrical, thermal, and
mechanical behaviors on rough surfaces, in which the elastic and plastic deformation of …

In the rough surface contact research, the real contact area has long been the primary focus,
however, the details of contact spots, such as the size, morphology, and distribution which …

The impact of non-Gaussianity on the statistical geometry of isotropic random rough surfaces
is analysed in this contribution. The non-Gaussian height distribution is modeled using the …

Modeling the elasto-plastic contact between rough interfaces may require high
computational effort as real surfaces present broad roughness spectra. In this work, we …

Traditionally, the research on thermal contact resistance based on real rough surfaces is
often limited to the uniform load. This study investigated the effects of the material, surface …

In the process of coal mining, storage, and transportation, the escape of coal dust restricts
the development of various aspects in China, such as environmental pollution, economic …

The goal of this work is to investigate the evolution of the running-in process and analyze the
running-in period. The present work improved the method, which analyzed the running-in …

This paper presents a novel and quantitative characterization method for the running-in
process through dimensionless real contact area. The traditional running-in criteria, such as …

The present article is dedicated to numerical methods for the simulation of the response of
PWR fuel assemblies under external mechanical loading such as earthquakes. It proposes …
