Abstract: A computer-implemented method for evaluating wear of a tire with a non-axisymmetric tread pattern, the method comprising: providing a wear model of the tire configured to convert a frictional energy rate into a wear energy rate; providing a first three-dimensional, 3D, model of the tire with the non-axisymmetric tread pattern; generating a plurality of simplified 3D models based at least in part on the first 3D model of the tire with the non-axisymmetric tread pattern; performing a plurality of steady-state transport analyses based at least in part on each one of the plurality of simplified 3D models; post-processing the results of each of the plurality of performed steady-state transport analyses; and evaluating the wear of the tire with the non-axisymmetric tread pattern based on the post-processed results of the plurality of performed steady-state transport analyses and the wear model.

Abstract: The present disclosure relates to a method for determining a critical slip distance, CSD, for a sample, the method comprising: providing a force to the sample towards a sliding surface; sliding the sample n times along the sliding surface over a plurality of intervals, the plurality of intervals having different widths w, n being an integer ?1; determining, for each width wi, a respective wear rate m(wi)=?M/(n*wi) of a plurality of wear rates m(w), wherein ?M is a weight difference of the sample after sliding the sample over n intervals of width wi as compared to before the sliding; and determining, based on the plurality of wear rates and the respective widths, the CSD as a width w0, wherein, for any (I).
