| 中文摘要: |
| 本文在文[1]的基础上,采用子结构法建立了多层复合板的边界元方法,对具有中心园孔[0°/90°]_s的层合板的层间应力作了计算,同有限元法的结果进行了比较,结果表明,应用边界元法处理这类问题,单元划分少,节约了计算机时,而且有较高的计算精度。 |
| 英文摘要: |
| The paper has established a boundary element method with isoparameter elements for 3-D composite laminate by introducing boundary element subrigion theory. The interlaminar stresses around the hole in a [0ooooooooooooooooo/90ooooooooooooo]s composite laminates containing a circular holes and loaded in uniaxial tension were analyzed. The results by this 3-D BEM are in good agreement with that by 3-D FEM. |
