摘要
复合材料具有较强的结构特性,是一种多相体材料。其力学性能及损伤破坏规律不仅取决于各组分材料性能,同时也取决于细观结构特征。采用细观力学分析研究复合材料宏观力学性能与细观结构参数之间的内在联系具有重要的科学意义和工程价值。论述了细观力学实验技术的理论基础和常用实验技术及进展,介绍了复合材料的细观力学模型的发展,综述了复合材料力学行为有限元分析的研究现状,并对这一学科的研究发展进行了简要评述与展望。
As a heterogenous material,composites have a significant structural mechanism.The mechanical behaviour and failure mechanism of composites depend significantly on its microstructure and the properties of each constituent.It is very important to study the relationship between the macromechanical behaviour and the microstructural parameters by using micromechanics.The experimental technic of micromechanics and its basic theory were introduced.The developments of the micromechanical models were presented.Then the developments of the numerical simulations,based on finite element method,of the mechanical behaviour were reviewed.Finally,the developing trends of this subject were discussed.
