摘要
应用粘弹性对应原理分析计算了界面材料在剪切方面服从Ｂｕｒｇｅｒｓ（四元件体）模型时，界面材料的粘弹性对单向纤维复合材料的有效性能的影响。结果表明，界面粘弹性只对单向纤维复合材料轴向剪切有效性能、横向有效性能产生对时间的依赖。而界面粘弹性对复合材料有效性能影响的大小与界面材料的特征时间大小有关。
Assuming that the viscoelastic interphase material deviatoric stress and strain can be described by the Burgers mod-el, we investigate the effect of interphase on the properties of unidirectional fiber composite with imperfect interphase. We do this on the basis of correspohdence principles for viscoelastic composites. The results obtained reveal that time dependence of effective properties produced by viscoelastic interphase is significant only for axial shear effective properties and transverse effective proper-ties.
