摘要/Abstract

摘要： 应用等效夹杂的细观力学理论,针对一种与取向相关的细长椭球颗粒填充情况,研究复合固体推进剂粘弹本构方程,发现颗粒对基体的增强效应主要体现在颗粒的纵向,得到了颗粒无序取向对基体的增强效应与颗粒单轴取向对基体沿该取向的增强效应之间存在一个定量的等效关系。

Abstract: The Eshelby’s equiralent inclusion theroy of micromechanics was used to analysis composite soild propellent filled leptosomatic ellipsoidal inclusions A new conclusion was discovered that the particles’ reinforce effects to matrices mostly were obtained from the particles’ portrait and onedimensional mechanical behavior of isotropic composite solid propellent with filler volume fraction f is equal to axial mechanical behavior of unidirectionally alignd leptosomatic ellipsoidal inclusions’ composite with filler volume fraction f d
