dc.description.abstractTraditionally in partial elastohydrodynamic lubrication (EHL)the contact through lubricating films has been modeled assuming random contarct and taking into accountratio of film thickness to r.m.s roughness(h/o).In some tribological situations to wear process can generate matching at asperity level in a case such as asperity level conformity the assement of contact is different from that based of random contact assumption,So it is nessery to find the effective roughness in light of such confermity.In the present study,characterzation of confermity has been attemped.First the exciting surface perameters are examind.It is shown that the confermity cannot be characterzied by these parameters.The contact has been modeld on the basis of composite profile optained through a cross-correlation aproach.It is shown that the effective r.m.s roughness would be significantly lower in a case of confermity as compared to that based of random contact assumption.Hence,this would result in reduced metal to metal contactfor the same film thickness.en
