## Abstract

For small ellipticities the Hertzian contact pressure and approach can be obtained to a good approximation by using the formulae for circular contacts»with an equivalent radius of curvature (AB) ˜"2, where A and B are the principal relative curvatures. For higher ellipticities (AB(A + B)/2)˜"3 should be used to find the contact area and pressure; an equivalent radius for finding the approach is also given. The ellipticity of the contact can be estimated from the asymptotic equation (alb) « (B/A)2/3. © 1985 by ASME.
