摘　　要：基于Eshelby-Mori-Tanaka细观力学理论及Weilbull统计学方程,建立了含界面损伤的复合固体推进剂黏弹性本构关系,研究了均匀开裂、环向开裂和顶部与底部开裂3种界面损伤模式对推进剂黏弹性本构关系的影响。数值分析结果表明:界面损伤对推进剂黏弹性本构关系影响显著,使其呈现明显的非线性黏弹性;不同界面损伤模式对推进剂黏弹性本构关系影响程度各异。Based on the micromechanical theory of Eshelby-Mori-Tanaka and Weibull＇s theory of statistics,the viscoelastic constitutive relationship of composite solid propellant with interfacial damage was established in this paper.The influence of interfacial damage for 3 kinds of uniform,circumferential and top spilt on the viscoelastic constitutive relationship of the propellant was studied.Numerical analysis showed that the influence of interfacial damage on the viscoelastic constitutive relationship of the propellant was obvious,and made it exhibit highly nonlinear viscoelasticity.The extent of different interfacial damage model affecting the constitutive relationship of the propellant was different.
