| 摘 要： | 本文讨论了在常规边界元法中引入概率分析的方法;给出了能够反应边界条件随机变化的边界元基本公式以及对由此而导出的结果进行概率分析的后处理方法;本方法在数值计算方面只需对原有常规边界元程序稍加改动便可实现。

| Abstract: | In this paper, how to incorporate random variables into boundary element methods ( BEM ) was discussed; the governing equations which can reflect random variation boundary conditions were given and the post-pr-occesses method for probabilistic analysis to the results from solving the governing equations was presented As a numerical example, a plane crack protlem is analyzed, in which the length of crAck and loading applied on it are taken as random Variables. |
