摘要：本章描述了先进纤维增强复合材料的弹性特性，从基本成分（即纤维和基体）的表征、测量和预测方面。弹性分析包括应用细观力学方法从基本成分预测层弹性性能，以及使用经典层合理论预测由以不同取向堆叠的多个层组成的复合材料的弹性性能。通过实例说明了理论分析的正确性，并对该方法的预测能力有了充分的认识。最后一节概述了基于全场测量的弹性特性识别方法。结果表明，这些方法是非常方便的各向异性和非均匀材料的弹性表征。
Abstract: This chapter describes the elastic qualities of advanced fibre-reinforced composites, in terms of characterization, measurement and prediction from the basic constituents, i.e. the fibre and matrix. The elastic analysis comprises applying micromechanics approaches to predict the lamina elastic properties from the basic constituents, and using classical lamination theory to predict the elastic properties of composite materials composed of several laminae stacked at different orientations. Examples are given to illustrate the theoretical analysis and give a full apprehension of its prediction capability. The last section provides an overview on identification methods for elastic proprieties based on full-field measurements. It is shown that these methodologies are very convenient for elastic characterization of anisotropic and heterogeneous materials.
