... done by Ren et al. (2010, “PEHL in point contacts,” ASME J. Tribol., 132 (3), pp. 031501) that focused on model development and validation, as well as investigation of fundamental PEHL mechanisms in smooth surface contacts. This part of the study is mainly on the PEHL behavior involving simple surface...
