摘要
以Signorini接触问题为例,讨论了接触问题边界变分不等式的边界元方法,得到了离散边界变分不等式近似解的存在唯一性定理,给出了近似解与精确解的误差估计表达式。
In this paper, by using Signorini contact problem was presented as an example, we study the boundary element method for the boundary variational inequality of contact problem, and derive the theorem of existence and uniqueness of the approximate of the discreted boundary variational inequality. Then the error estimates expression between the approximate and exact solution is given.
