A Reversed Solution for the Elastic Contacts Between Symmetrical Fourth Order Polynomial Surfaces

The paper advances a combined, analytical-numerical solution for the elastic contacts between symmetrical, fourth order polynomial surfaces. This is based on a proposal for contact area and pressure distribution which must generate forth order polynomials for the deformed surface of the halfspace inside contact area. To check this proposal, the normal displacements inside contact area are computed numerically. These agree well with a fourth order polynomial. The effect of contact area and pressure coefficients upon the shape of pressure distribution is evidenced.
