| 摘 要： | 本文导出基于边界元理论的一种数值方法，用以计算正交层合板的温度应力，对于板的平面问题的应力分析，采用格林基本解答做为权函数，导出板的边界积分方程。对于有侧向载荷的板壳，同时采用两种不同的基本解为权函数，建立一组边界积分方程。数值计算结果收敛，和实验结果基本相符，证实了方法的可行性。

| Abstract: | A numerical method based on boundary element technique is proposed in this paper for the solution of thermal stresses in composite laminates. Green foundamental solution was used as weighting function for the in plane problems , and two different foundamental solutions was used as weighting functions for the plate bending problems . It is found that the numerical solutions are convergent and are in good coincidence with experimental results. |
