Abstract. A numerical method for elastic contact analysis valid at any loading eccentricity is refined in this paper by removing the need for an additional Newton Raphson outer loop, which was present in a previously proposed solver. Surface separation equation and pressure correction instruction are modified by adding a term linear in coordinates. Numerical simulations are performed on a circular rigid flat ended indenter with rounding radius pressed eccentrically against an elastic half-space, and the eccentricity effect upon stress state induced in the half-space is assessed.
