... was established with discrete element method. Then, the correlation law between sliding-rolling ratio and force chain evolution properties was calculated and analyzed with PFC2D software platform. Findings Numerical calculation results show that the dynamic fluctuation property of force chain is existed...

... Discrete element method Friction and wear Fractal theory Wavelet analysis The frictional resistance between tire and road surface is of great importance for driving safety. Previous studies have clearly classified the irregularities of pavement textures as macro-texture (0.5–50mm) and micro...

... In this paper, a plane shear cell under granular lubrication is established by the discrete element method to study the flow constitutive relation and its mechanical mechanism of the hard granular lubricants. Findings Research results show that the flow regimes in granular flow lubrication strongly rely...

... lubrication theory. Design/methodology/approach A granular flow lubrication research model is constructed by the discrete element method. Using this numerical model, the mesoscopic and macroscopic responses of stick-slip that influenced by the shear velocity, and the influence of the shear velocity...
