摘要
鉴于Eshelby张量在整个微分法的"取出-添入"过程中的变化对等效模量变化影响较小,论文推出了微分法的近似显式解.该近似解形式简捷,计算方便,不仅适用于球形颗粒夹杂,对随机短纤维夹杂等情况也同样适应,所得结果与实验数据非常接近.
Considering that the effect of Eshelby＇s tensor in view of the entire differential method of ＇extraction-accession＇ during the process of change in modulus variation is less,an approximate explicit expression of the differential method is established in the paper.The simple form of approximate solution is facilitating to calculation.The expression can be fit very well for spherical inclusions and stochastic short fiber inclusions.It shows that the theoretical prediction results are in good agreement with the existed experimental data.
