Finite element based modeling of multi-asperity contact and validation of Greenwood-Williamson model
… this model is often cited as it is ignoring of asperity interaction effects. This thesis aims to validate the Greenwood-Williamson model by using the finite element method to study multi-asperity contact and asperity interaction effects. The first step in the study of multi-asperity contact was …

Tribological studies of micro/nanoscale thin solid films
… a hard layer is coated on a soft substrate, both asperity interaction and soft substrate deformation should be considered. Fourth, the wear behavior of a layered sphere at the sliding inception was analyzed based on the finite element approach. The relationships among potential wear, material …

An Investigation into the Effects of Asperities on Geomembrane/Geotextile Interface Shear Characteristics
… and mechanism, as well as to identify the asperity parameters combination which optimizes the GMB/GTX interface shear strength. The GMB/GTX interface shear tests were conducted according to ASTM D5321, under saturated conditions with the “305 mm by 305 mm” direct shear box at applied normal …

Multi-Length Scale Modeling of Rubber Tribology For Tire Application
… of surface roughness, substrate condition and asperity interaction. A finite element simulation of rubber block sliding on a rough substrate is performed using a multiscale technique for estimation of friction and contact mechanics under dry condition. The estimated contact mechanics and …
