It is emphasized that the assumption of a perfect Gaussian heigth distribution, including infinite tails, may be a strong one when studying adhesion in rough surfaces.en0301-679X2017435440Elsevier ScienceAdhesionDMT adhesion modelGreenwood-Williamson's theoryRough surfacesTechnikIngenieurwissenschaftenJournal Article10.1016/j.triboint.2017.01.003Other
