Stochastic process model of rough surface contact
Yang Xu, Yunong Zhou
The paper reviews Persson's stochastic process model for elastic contact between rough surfaces, explaining how to solve for contact pressure and gap distributions using partial di…
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…
A stochastic model for elastoplastic contact of rough surfaces incorporating scale-dependent hardness
Yang Xu, Hengxu Song, Jianqiao Hu
The stress concentrations caused by inherent roughness of natural and manufactured surfaces often induce plastic deformation at contact interfaces, a challenge compounded by compet…
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…
Revisiting the diffusion equation derivation in Persson's theory of contact
Yang Xu, Siyuan Yang, Yunong Zhou +1
In Persson's seminal work on tire-road interaction (Persson, J. Chem. Phys. {\bf 115}(8), 2001), he ingeniously derived a diffusion equation in Appendix B to characterize the evolu…
