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。 According to the mesoscopic mechanics theory of equivalent inclusion, aiming at the orientation-related slender ellipsoid particle filling, the viscoelastic constitutive equation of the composite solid propellant is studied. It is found that the reinforcing effect of the particles on the matrix is ​​mainly reflected in the longitudinal, It is found that there is a quantitative equivalent relationship between the enhancement effect of disordered orientation on the matrix and the enhancement effect of uniaxial orientation on the orientation of the matrix.
