| 摘 要： | 从连续损伤力学出发,利用Kachanov提出的损伤演化定律来表征改性双基推进剂的破坏损伤特性.利用等速力破坏试验拟合损伤方程参数,利用损伤方程计算了等速位移下的损伤过程,进行了等速位移破坏试验,利用建立的损伤演化模型计算等速位移拉伸时的损伤演化过程.结果表明,起初损伤为0,损伤缓慢增长,力值达到某一程度时损伤迅速上升直...

| Abstract: | Based on continuous damage mechanics,the damage law proposed by Kachanov was used to describe the damage process of modified double-base propellant.Constant-force damage tests were carried out to fit damage parameters.Constant displacement tests were also carried out,and the damage values of propellant were calculated in constant displacement process.The damage evolution process was calculated by using damage evolution model.The results show that the initial damage value is zero,and then damage value increa... |
