This paper discusses a new and innovative numerical procedure for evaluating and monitoring contact stresses in the mating surfaces of propulsion systems. The procedure is intended to extend the range of applicability and the accuracy of contact stress analyses. Originally proposed by Burton Paul, et. al., (1981) the procedure is based upon fundamental solutions from the theory of elasticity. It is an iterative numerical procedure. It is believed that the method has distinct advantages over the classical Hertz method, the finite-element method and over existing approaches with the boundary element method. Several examples are discussed. Favorable comparisons are obtained with classical results. Applications with mating element of propulsion systems are discussed.
