摘要
参考金属材料J积分的测试方法,测定了某型固体火箭发动机装药的断裂韧性.采用有限元的方法,分析了三点弯曲实验,得出了断裂韧性J_((?)C)的数值分析结果并对两者进行了比较.
The fracture of propellant is tested according to the J integration method of metal fracture. Finite element analysis of three-point bend test is carried out, and both the data from computation and test are compared.
