Finite element modelling and experimental study of oblique soccer ball bounce [PDF]
, 2011 In this study, we develop a finite element model to examine the oblique soccer ball bounce. A careful simulation of the interaction between the ball membrane and air pressure in the ball makes the model more realistic than analytical models, and helps us

Sealing is at the Origin of Rubber Slipping on Wet Roads
, 2004 Loss of braking power and rubber skidding on a wet road is still an open physics problem, since neither the hydrodynamical effects nor the loss of surface adhesion that are sometimes blamed really manage to explain the 20-30% observed loss of low speed ...

Simulation for rubber friction on self-affine surface based on energy method
The Journal of Engineering, 2019 Here, the authors propose an energy method to obtain the friction coefficient of a rubber block sliding on self-affine substrates via simulation. Due to the multi-scale property, the rough surfaces are modelled with four harmonic rigid frictionless roads.

Experimental Investigation of the Performance of SBR and RSS Materials as a Sliding Bearing Element
Crystals, 2022 Conventional bearing systems and materials, which are important components of machine elements, have often failed to fulfil requirements, especially in places where sealing is required. In such cases, sliding bearings with PTFE- and NBR-based polymer and

General contact mechanics theory for randomly rough surfaces with application to rubber friction
, 2015 We generalize the Persson contact mechanics and rubber friction theory to the case where both surfaces have surface roughness. The solids can be rigid, elastic or viscoelastic, and can be homogeneous or layered.

Theory of rubber friction: Nonstationary sliding [PDF]
Physical Review B, 2002 When rubber slides on a hard, rough substrate, the surface asperities of the substrate exert oscillating forces on the rubber surface leading to energy ``dissipation'' via the internal friction of the rubber. In this paper we extend an earlier published theory [B.N.J. Persson, J. Chem. Phys.

Friction, 2023 Many rubber friction theories or some method combined theories and field-experiments are employed to evaluate the pavement skid-resistance deterioration due to the evolution of surface textures.

Rubber friction on wet and dry road surfaces: the sealing effect
, 2005 Rubber friction on wet rough substrates at low velocities is typically 20-30% smaller than for the corresponding dry surfaces. We show that this cannot be due to hydrodynamics and propose a novel explanation based on a sealing effect exerted by rubber on

A Digital Twin for Friction Prediction in Dynamic Rubber Applications with Surface Textures
Lubricants, 2021 Surface texturing is an effective method to reduce friction without the need to change materials. In this study, surface textures were transferred to rubber samples in the form of dimples, using a novel laser surface texturing (LST)—based texturing ...
