非完美界面多边形夹杂复合材料弹性场研究

导出了在非完美界面下，具有均匀本征应变的多边形夹杂复合材料位移场的计算公式，利用边界单元法求解了均匀剪切本征应变下多边形夹杂内应变场的分布。数值结果表明界面连结的完好与否对夹杂内部应变分布有比较明显的影响；随着界面缺陷程度的加剧，多边形内的应变偏离完好界面情形的相应应变就越大，这与实际情况相符。

Research for the Elastic Fields of Polygon-shaped Inclusion Reinforced Composites with Imperfect Interface

In this paper, the displacement field in an infinite elastic body containing an arbitrary convex polygon-shaped inclusion with uniform eigenstrains is investigated under the condition of imperfect interfaces. Using the boundary element method, the solution for the strain field with uniformly tangential eigenstrains is obtained. It is found that the strain distribution is significantly influenced by the condition of interface and the discrepancy of the strain is increasing in the polygon shaped inclusion along with the increase of interfacial damage. This corresponds to the fact.
