本文综述了关于复合材料的各种经验强度理论。首先简要地介绍了基于破坏模式相互独立假定的强度准则,这些准则通常以几个相互平行的表达式表达。然后叙述根据破坏模式相关假定建立的多种强度理论,重点讨论了张量多项式型的强度准则,这些准则以应力分量的统一的表达式表述。简述了建立和验证强度准则的实验方法以及实验结果与理论的比较。
This article reviews various empirical strength theories for composites. First, we briefly introduce the strength criteria based on the mutually independent assumptions of failure modes. These criteria are usually expressed in terms of several mutually parallel expressions. Then, based on the multiple strength theories established under the assumptions of failure modes, the strength criteria of tensor polynomial types are mainly discussed. These criteria are expressed in terms of the unified expressions of stress components. The experimental methods for establishing and verifying the strength criterion and the comparison between the experimental results and the theory are briefly described.
