A discrete boundary condition on an arti®cial boundary is obtained for some second-order elliptic boundary value problems with interface. The problem is reduced to a problem without singularities, and the standard ®nite element method is used to solve this problem. Some numerical examples are given.

✦ Synopsis
Discrete boundary conditions on an artificial boundary are obtained for the elasticity problems with singularities. An iteration method is designed to solve the boundary value problem by using the discrete boundary conditions. Some numerical results are given, which demonstrate the effectiveness of the numerical method.
