摘要:

本文把复合材料层合板中第K层板裂纹尖端附近应力场的表达式代入Tsai-Hill准则,得到了复合材料层合板中第K层板裂纹尖端附近的塑性区尺寸因子的公式,从而可以确定其塑性区尺寸,这为在复合材料层合板中运用断裂力学判据提供了条件。

Abstract:

After the expression of stress field near the tip of a crack of the k-thlaminated plate of the composite laminate is substituted into Tsai-Hill Criterion,a formula of evaluating the plastic zone size factor near the tip of a crack of, the k-th laminated plate of the composite laminate is obtained in this paper. Hence, its plastic zone size can be determined,which makes it possible to apply Fracture Mechanics Criterion to the composite laminate.
