| 摘 要： | 对固体推进剂双轴板条试件进行了有限元分析，并考虑了粘弹性对应力结果的影响，分析结果表明，双轴板条试件中心域为平面应变状态，与发动机药柱中部内孔表面相似，并给出了计算杨氏模量所需的修正系数。

| Abstract: | finite-element method is used to analyze the propellant biaxial strip specimen. The influence of visco-elastic behavior on stress condition is also considered in the analysis. Analytical results indicate that the center area of the strip specimen is in a condition of plan strain which is similar to surfaces of the center port of propellant gains.The correction coefficients for the Young's modulus calculation are suggested. |
