Abstrakt: The strength of the contact between high-order polynomial surfaces, optimized as to induce a close to uniform pressure distribution on the contact area, is investigated by computer simulation. Three type of contact conditions are examined, i.e. frictionless, gross slip and partial slip, and the depth and magnitude of the maximum of von Mises equivalent stress field is assessed using the Greens functions for the elastic half-space and a multi-summation technique based on the fast Fourier transform and on the convolution theorem. The set of simulations allows formulating recommendations concerning the use of punches bounded by high-order polynomial surfaces to increase the load-carrying capacity of the non-conforming mechanical contact.
