摘要: 本文作者采用细观力学阻尼理论,分析SMA纤维和普通纤维混杂的单向单层材料的阻尼性能,给出材料在6个方向上的阻尼性能计算公式,通过数值算例讨论NiTi的阻尼混杂效应。Abstract: The damping properties of a SMA hybrid composite lamina with fibers reinforced unidirectionally are investigated by using a simplified micromechanic damping theory. The analytical equations corresponding to all the six in plane and out-of-plane damping parameters are presented. Numerical studies are carried out to demonstrate the damping enhancement of hybridization effect by embedding NiTi fibers.
