The crack and the contact pressure are replaced with the continuous arrays of dislocations and the point forces respectively, the densities of which are the unknown functions of the singular in- tegral equations. These singular integral equations are reduced into a set of algebraic equations through the concept of the boundary collocation. Some of the numerical results show that the He
