摘要
为了研究薄体和涂层结构,提出求解三维弹性薄体和涂层问题的虚边界元法,建立了弹性涂层基本列式,给出了求解弹性薄体和涂层结构问题的新方法。数值算例表明,虚实边界的距离选取与边界离散单元数有关,数值结果与精确解结果一致,方法简单、易于程序设计。
In this paper,the virtual boundary element method（VBEM）for solving thin body problems and coating problems in 3Delastic theory is presented,which not only provides a new approach to deal with such problems,but also extends the application fields of VBEM.Numerical examples demonstrate that the proposed method can effectively solve thin body and coating structure problems even when their thicknesses are as small as the nanometer scale,and that the VBEM is a simple and powerful tool for solving 3Dthin body problems and coating problems.
