边界元法解各向异性应力集中问题

Boundary element method for solving the stress concentration problem in anisotropic plate

针对各向异性板的应力集中问题,以复变函数表达的基本解作为权函数建立了边界元法格式,给出了含圆孔的各向异性板应力集中问题的数值算例,通过数值结果与有限元方法的比较可知:边界元法对于各向异性板应力集中问题的求解具有较高的计算精度和广泛的适应性。

Using the fundamental solution of anisotropic plate described with a complex variable function method as weight function, this paper established the boundary element format of general anisotropic problem of plane. Numerical examples of the stress concentration problem in anisotropie plate with a circular hole are presented and the numerical results are compared with that solved by the finite dement method. The illustration demonstrated that the anisotropic boundary dement method has higher calculating precision in solving stress concentration problems and can be widely used.
