A method for calculating the elastic-stress distribution in two axi-symmetrical conical bodies caused by frictionless contact between them is described. Finite-difference methods were used to solve the governing differential equations. Equilibrium and compatibility over the contacting surfaces was achieved by using the finite-difference solutions to derive a matrix of influence coefficients. By means of an iterative technique, using this matrix, the portion of each surface in the contact zone and the stresses on it were found. With equilibrium and compatibility achieved, the stresses throughout the body of each component were calculated. A selection of results for one case is given.
