A simple procedure of obtaining flexibility matrices in terms of contact pressures at possible contact points of two bodies allows the frictionless contact pressures to be solved as a quasi‐linear problem. Iteration is limited in general to very few cycles and, as small matrices are handled, can be very economical. Excellent accuracy of this procedure is demonstrated.
