| 摘 要： | 本文提出了求解平面热弹性问题的应力边界元法。利用应力法由平面热弹性问题的基本方程出发,简要地叙述了边界积分方程的建立,给出了位移单值条件。这种方法适用于应力边界值问题。作为数值计算例,计算了圆形区域和具有偏心圆孔的圆形区域的热应力,得到了满意的结果。应力边界元法也可应用于平板弯曲问题。

A BOUNDAY ELEMENT METHOD BASED ON STRESS FOR PLANT THERMOELASTIC PROBLEMS |
| |
| Abstract: | In this paper the boundary element method based on stress for solving plane thermoelastic problems is proposed.Using the basic equation of a plane thermoelastic problem and the stress method,the derivation of boun- dary integral equations and the single-valued conditions for the displace- ments are briefly mentioned,It is suitable for stress boundary problems. The numerical results are obtained for the calculation of thermal stress in the circlar region and the circular region with an eccentric circular hole, This method can be further extended to the plane bending problems as well. |
