复合材料细观损伤研究方法可以在细观的尺度上对复合材料的力学性能和损伤失效进行研究.通过细观尺度上的胞元建立损伤萌生与演化模型,根据细观损伤演化模型确定细观损伤变量.当细观损伤变量达到阀值时可预报复合材料的强度和疲劳寿命等宏观性能.细观损伤有限元分析已成为对理论模型进行修正的重要手段,可以用理论分析与有限元模拟相结合的方法研究复合材料的力学行为.为了更好的为相关研究工作提供参考,对复合材料细观损伤研究进展情况从理论研究和有限元研究两方面做了一个回顾和梳理.

Meso-damage research method of composites is a new subject which studies microstructure damage and evolution through micro cell, and deduces material macro mechanical properties through volume average of micromechanical results when the meso-damage variables reached the threshold values. Comparison can be made between meso-damage simulation results and meso-damage theory analysis results and the trend is the combination of the two methods. In order to offer reference for related researches, the paper reviewed the recent development of meso-damage theory from two aspects of theoretical research and finite element researches of composites.
