摘要：
In this paper the Tikhonov regularization method is analysed for the ill-conditioned system of linear equations which arises from the discretization of an ill-posed boundary value problem in linear elasticity. The choice of the regularization parameter is achieved according to the L-curve method. Then the regularization method is numerically implemented using the boundary element method (BEM).
