Miscalculation of film thickness, friction and contact efficiency by ignoring tangential tractions in elastohydrodynamic contacts George K. Nikas KADMOS Engineering Ltd. 3 Princes Mews, Hounslow, TW3 3RF, England E-mail: nikas@blueyonder.co.uk Abstract Traction in elastohydrodynamic contacts causes normal surface displacements, affecting the lubricant film thickness. This is ignored in the vast majority of published theoretical studies and fil
