摘要
不同介质的组合结构 ,对其结合面附近域进行准确分析计算的研究 ,具有理论意义和应用价值。本文依据虚边界元法 [1 ,2 ]导出了不同介质组合结构弹性力学问题的求解方程。通过数值算例结果与解析解和有限元解的比较 。
In view of the composite structures of different mediums, there are either theoretical meaning or the value in application about the calculating analysis on researching its combined area. In this paper, a numerical method is presented to solve the composite structures of different mediums with virtual boundary element. Comparing with analytic solution and finite element solution, the examples proved the efficiency and reliability of the presented method.
