Stochastic process model of rough surface contact
Yang Xu, Yunong Zhou
The stochastic process model of rough surface contact, widely known as Persson's theory of contact, serves as a representative multi-scale model that has been extensively applied a…

Mass weighting algorithm optimizes Fourier-based physics-informed neural network in adhesive contact mechanics
Yunong Zhou, Kaifeng Huang, Chaofan Du +2
Physics-informed neural networks (PINNs) for elastic contact mechanics suffer from a spectral stiffness imbalance,that is, the elastic kernel grows linearly with wave number, causi…

Field-theoretical approach to estimate mean gap and gap distribution in randomly rough surface contact mechanics
Yunong Zhou, Hengxu Song, Zhichao Zhang +1
We extend the statistical field-theoretical framework of rough surface contact mechanics to characterize the interfacial gap between an elastic half-space and a randomly rough surf…
