COUNTACT (Counterformal Contact of Two Elastic Bodies) is an all Fortran computer program for the solution of stress analysis between two elastic bodies in counterformal contact. It is used to find the pressure distribution between the two bodies, the boundary of contact patch, and the total load corresponding to a given depth of penetration. The program COUNTACT has two versions: COUNTACT-1 for those bodies with a contact patch having one axis of symmetry, and COUNTACT-2 for those bodies whose contact patch has two axes of symmetry. Descriptions of the program variables, input, output, and method of analysis are given. Instructions for problem modelling, preparation of input data, and solutions of sample problems, are included. The general approach to writing a user-supplied subroutine required by the program is discussed.
