SMA纤维复合材料超弹性滞回特性研究

A STUDY OF SUPERELASTIC HYSTERETIC PROPERTIES OF SMA FIBER COMPOSITE

  • 摘要: 本文对SMA纤维复合材料的轴向超弹性滞回特性进行理论分析,首先采用三相同心圆柱体模型和多胞模型计算材料的宏细观力学性能及其纤维轴向应力应交响应曲线.超弹性滞回特性的数值计算则采用平均抛物线插值法,最后给出环氧树脂/Ni-44.8wt%Ti纤维复合材料的具体数值结果.

     

    Abstract: Theoretical analysis and numerical approach were given for the longitudinal superelastic hysteretic properties of composite with SMA fibers in this paper. A concentric three-phase cylinder model and multicell micromechanics mothod were used to predict equivalent properties of SM composite and longitudinal response of SMA fiber composite. An average parabolic interpolation approach was utilized for the numerical integration related to equations (10) and (11). The numerical results for an Ni-44.8wt% Ti/epo...
