A three-dimensional periodic contact problem in the theory of elasticity for a wedge is investigated when an infinite system of identical punches are arranged on one face of the wedge along the edge (at an equal distance from the edge and with equal intervals between neighbouring punches). Identical normal embedding forces are applied to the punches and friction forces are neglected. The other edge of the wedge is rigidly clamped. Without loss of generality of the approaches, the wedge material is assumed to be incompressible. The problem is reduced to an integral equation, from the kernel of which the principal part corresponding to an elastic half-space is separated out. The effect of the edge of a three-dimensional wedge on the contact pressure distribution and the mechanical characteristics of the contact is studied. A regular asymptotic method of solution is used for specified elliptic contact areas. When the contact areas are not known in advance, the method of non-linear boundary value integral equations is used. Calculations were carried out for elliptic and conical punches.
