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…
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…
Stochastic process model for interfacial gap of purely normal elastic rough surface contact
Yang Xu, Junki Joe, Xiaobao Li +1
In purely normal elastic rough surface contact problems, Persson's theory of contact shows that the evolution of the probability density function (PDF) of contact pressure with the…
