Progress in Numerical Simulations and Mesoscopic-mechanical Models of Fiber-reinforced Composites

纤维增强复合材料是一类高比强度、高比刚度的新兴结构材料。开展该材料的强度分析和破坏过程模拟具有重要的科学意义和工程价值。介绍了纤维增强复合材料的细观力学模型的发展过程,综述了引入统计概念的复合材料力学行为有限元分析的研究现状,并展望了其发展趋势。

Fiber-reinforced composites were a new kind of structural material with high specific strength and high specific rigidity. It was very important to analyze and simulate the mesoscopic-mechanical behaviors of fiber-reinforced composites. The developments of the mesoscopie-mechanical models of the material were presented. Then the developments of the numerical simulations, based on finite element method and Monte Carlo method, of the mechanical behavior were reviewed. Finally, the development trends were prospected.
