| 摘 要： | 本文提出了处理夹杂问题的自洽有限元法。它以自洽模型为基础,利用有限元迭代法计算有效介质的平均弹性性能。作为应用,本文利用该方法计算了单向短纤维增强复合材料的平均弹性模量,并比较了纤维的几何形状对复合材料平均弹性性能的影响。数值结果与实验值吻合较好。

| Abstract: | The paper presents a self-consistent finite element method (SCFEM)dealing with inclusion problems. Based on self-consistent model, the average elastic properties of effective medium are calculated by the fi nite element iteration procedure. As applications of this method, the average elastic moduli for unidirectional short-fiber composites are obtained and the effect of fiber geometry on average elastic properties of composites are in-vestigated. The numerical results agree well with those of experiments. |
