| 摘 要： | 为研究复合推进剂AP/基体界面脱湿机理,建立了基于粘聚力界面模型的双尺度有限元损伤分析平台.为确定界面模型的输入参数,采用点滴法和Washburm毛细管上升法,分别测得基体与AP颗粒的接触角,再经Young's方程计算得到界面的粘附功.通过对不同体积分数下简化配方推进剂试件的拉伸试验结果与计算结果的对比显示,两者具有较...

| Abstract: | A bi-scale FEM damage analysis platform based on cohesive interface model and mathematical theory of homogenization was built to get macro mechanism behavior and dewetting mechanism of composite propellant.By using drop and Washburm method,the contact angle of bond and AP particle were obtained.Using Young's equation,the cohesive work was calculated as the input parameter of cohesive model.The simulation result was tested by tensile test of simplified propellant with different volume fraction.The results sh... |
