| 摘 要： | 利用零普金森杆加载系统对氮化硅陶瓷的动态冲击应力－应变特性作了实验研究，并与氮化硅陶瓷的静态压缩应力－应变特性作了比较，结果表明，氮化硅陶瓷在动态冲击应力作用下，应力－应变关系呈现非线性行为，而在静态压缩应力条件下，应力－应变关系主要表现为准线性行为。

| Abstract: | The dynamic impact stress vs strain characteristic of St,N.ceramics is tested by use of a Hopkinson pressure bar,and is compared with static compressive stress vs strain characteristic.It is shown that the stress vs strain characteristic of Si3N4 ceramics presents non-linear behavior under dynamic impact loading. However,the stress vs strain characteristic of Si3N4 ceramics is mostly quasi -linear behavior under static compressive loading. |
