应力有限元分析中边界应力计算的一种方法

A Method of Calculating the Boundary Stresses in the Stress Analysis by FEM

    摘要
  • 摘要: 本文利用边界元法中边界应力的计算方法对有限元应力分析中原边界应力计算方法加以改进,并给出几种不同格式的边界应力计算公式和算例。该方法使用较方便,计算结果的精度比原方法有一定提高。

     

    Abstract: In this paper a method which improves the calculation of boundary stresses in FEM by utilizing the formulae of boundary stresses in BEM is described. Some examples are presnted.The method is easier to use and the accuracy is higher.
