| 摘 要： | 本文对受弯正交复合材料板进行了理论断裂分析。采用了最近发展的基于能量的叫做“Z准则”的断裂准则。推导出了受弯复合材料板裂纹尖端附近的应力场、应变场、S-因子和Z-因子等的计算公式。这些公式对工程师们在复合材料结构的研究中进行断裂分析或实验研究是非常重要而有用的。

| Abstract: | In this paper, a theoretical fracture analysis for orthotropic composite plate under bending condition is studied. The methods of applying a recently developed energy based fracture criterion called "Z Criterion" are also introduced. Equations have been derived for calculating stress fields, strain fields, S-factors and Z-factors near crack tip in composite plates under bending conditions.Those equations are very important and useful for engineers doing fracture analysis or experiment studies in composite structure research. |
