使用最近开发的微观力学模型“桥接模型”可以简单地模拟超出弹性变形范围的纤维复合材料的整体热机械性能。模拟中仅需要复合材料的原位组成纤维和基体特性以及纤维体积分数。本文对这种通用且易于实现的微观力学模型进行了回顾和总结。演示了应用该模型预测单向层合板和多向层合板的各种性能，包括热弹性行为、弹塑性响应、极限失效强度、高温强度、疲劳强度和 S-N 曲线。因此，建议使用经过实验数据适当校准的桥接模型，可以通过识别合适的组成材料、其含量及其几何排列来为复合材料设计提供信息。还解决了有关桥接模型应用的一些技术问题。 (C) 2001 Elsevier Science Ltd. 保留所有权利。
The overall thermal-mechanical properties of a fibrous composite out of an elastic deformation range can be simply simulated using a recently developed micromechanics model, the Bridging Model. Only the in situ constituent tiber and matrix properties of the composite and the fiber volume fraction are required in the simulation. This general yet easy-to-implement micromechanics model is reviewed and summarized in the present paper. Application of the model to predict various properties of unidirectional laminae and multidirectional laminates, including thermoelastic behavior, elasto-plastic response, ultimate failure strength, strength at elevated temperature, and fatigue strength and S-N curve, is demonstrated. It is suggested that use of the bridging model, appropriately calibrated with experimental data, can therefore inform composite design by identifying suitable constituent materials, their contents, and their geometrical arrangements. Some technical issues regarding applications of the bridging model are also addressed. (C) 2001 Elsevier Science Ltd. All rights reserved.
