In this paper, we obtain a new system of canonical integral equations for the plane elasticity problem over an exterior circular domain,and give its numerical solution. Coupling with the classical finite element method, it can be used for solving general plane elasticity exterior boundary value problems.This system of highly singular equations is also an exact boundary condition on the artificial boundary.It can be approximated by a series of nonsingular integral boundary conditions.
