Abstract
The capability of complex micro-texturing technique for tuning the transition from static to kinetic friction is investigated based on a two-dimensional (2D) lattice spring block model. Results reveal that implementation of micro-texturing remarkably decreases the static friction coefficient even for a small amount of covering percentage, however this effect gets slight after covering percentage of about 10%. It is observed that elongation of micro-texturing cavities perpendicular to the sliding direction can improve its reducing effect on static friction coefficient. Furthermore, as simulations prove, using complex shapes of micro-texturing cavities with sharp vertexes slightly modifies the frictional response.
