考虑初始缺陷的HTPB推进剂粘超弹本构模型OA北大核心CSCDCSTPCD
Visco-hyperelastic Constitutive Model of HTPB Propellant Considering Initial Defects
为研究端羟基聚丁二烯(HTPB)推进剂存在初始缺陷对其宏观力学性能的影响,对定制的不同界面缺陷含量的HTPB推进剂开展了多步松弛和单轴拉伸试验.获得了HTPB推进剂的平衡响应曲线和拉伸曲线.采用Ogden模型拟合了不含缺陷的HTPB推进剂的平衡响应曲线,引入应变率参数M来描述HTPB推进剂单轴拉伸曲线的率相关特性.通过该曲线拟合,得到了不含缺陷的HTPB推进剂的粘超弹本构模型参数.考虑了缺陷的影响,通过引入初始缺陷损伤因子f,构建了含初始界面缺陷…查看全部>>
To study the effect of hydroxyl terminated polybutadiene(HTPB) propellant with initial defects on its macroscopic mechanical properties,the multi-step relaxation and uniaxial tensile tests of the home-made HTPB propellants with different content of initial interface defect were conducted and the equilibrium response curve and tensile curves of HTPB propellant were obtained.The equilibrium response curve of HTPB propellant without initial defects was fitted b…查看全部>>
