| 摘 要： | 利用细观力学的Eshelby等效夹杂方法研究了复合材料的粘弹性问题。通过时间域内的Laplace变换及对应性原理,将问题线性化,预报了颗粒增强复合材料的蠕变本构关系,给出了材料模量随时间、夹杂体积分数的变化规律,并与实验结果对照,吻合较好。

| Abstract: | The Eshelby equivalent inclusion method is used to study the viscoelastic problem of polymeric composite materials. The creep constitutive relations of particulate reinforced composites are investigated by Laplace transformation and the corresponding principle. The variation of the moduli of materials with time and inclusion volume fraction is given, and the theoretical prediction coincides with experimental results. |
