复合材料层合结构层向理论及应用进展

层向理论是由Reddy提出来的一种用于精确分析复合材料层合结构的三维板壳分析理论。由于不引入任何的变形和应力假设条件,因此相较于传统的等效单层板理论,层向理论在分析大厚度复合材料层合板壳结构的静动态响应及其局部层间效应时具有较大的优势。系统地综述了层向理论近年来的研究进展、数值解法及其应用情况。具体包括:层向理论的基本原理及发展现状、基于层向理论的有限元方法及改进模型、层向理论在复合材料层合结构静动态响应及含损伤问题领域的应用等。并对该理论可进一步拓展的研究方向进行了展望。

Review of layerwise theory for composite materials laminated structures and its applications

Layerwise theory, proposed by Reddy, is a 3D analysis method for accurately analyzing composite laminated plates and shells. Without introducing any deformation and stress hypothesis, layerwise theory, compared with the classical equivalent single layer theories, has greater advantages for static and dynamic responses analysis of thick composite laminated plates and shells, especially for local interlaminar effects analysis. A review and recent research progress of the layerwise theory were presented, and its numerical solutions and applications were demonstrated as well. The basis of layerwise theory and its recent development were introduced. The implementation of layerwise finite element method and its refined models were discussed. The employment of layerwise theories for conducting static and vibration analyses and the damage model analysis of composite laminated plates and shells were outlined. And several future research trends were recommended in the end.
