本文将Signorini问题化为边界上的变分不等式，并给出了求解该问题的直接边界元方法。此外，给出了Signorini问题的近似解的误差估计。此外，我们表明，Signorini问题可以制定为一个鞍点问题的边界。
In this paper, a Signorini problem is reduced to a variational inequality on the boundary, and a direct boundary element method is presented for its solution. Furthermore, error estimates for the approximate solutions of Signorini problems are given. In addition, we show that the Signorini problem may be formulated as a saddle-point problem on the boundary.
