| 摘 要： | 基于细观力学方法分析了智能复合材料中的微裂纹与夹杂的相互作用，导出了裂纹扩展的能量释放率，分析了形状记忆合金的多机理联合增韧作用．研究表明，智能复合材料具有相变和异性夹杂的双重增韧机理，而且其韧度可由外部条件控制，因而有可能使这种复合材料展示出超级力学性能

| Abstract: | The interaction between the inclusions and cracks was accounted for by means of micromechanical method. The analytical formulas were derived for energy release rates of a microcrack in the smart composites. This work shows that the multimechanisms contribute to toughening of the smart composite reinforced by SMA. The toughness can be controlled by the environmental variables. |
