Local yield map and elastic-plastic deformation map of hard coating with lubricative particles under sliding

In this paper, the von Mises stress distribution in coatings with particles under sliding was analyzed by the finite element method. An elliptical distribution of normal and traction contact pressure was assumed for the analysis of von Mises stress for various combinations of the coating thickness, yield strength and the friction coefficient. The positions of yield and the critical contact pressure of yield were found with the calculated result. The local yield map and the deformation map were introduced in relation to the yield strength, coating thickness friction coefficient, critical contact pressure, etc. (C) 1999 Elsevier Science S.A.
