| 摘 要： | 对受子弹正向撞击的铝合金圆板进行了动力反直观行为的实验研究。描述了不同撞击速度下板的响应模式，发现了圆板中的反直观现象，即板的最终变形与子弹撞击方向相反，并记录了板在整个变形过程中典型点的位移历史曲线，进一步证实了结构动力响应的反直观行为是一种客观存在的弹塑性动力行为。

| Abstract: | Tests were performed to investigate the dynamic anomalous response of circular plates impacted by projectiles.Different response modes of the circular plates under different impact velocities have been described.Here exists anomalous response in the narrow velocity ranges.'Anomalous' here means that the final deflection may be in the direction opposite that of the load.Displacement-history curves of the representative points in the circular plates were experimentally recorded.Experimental results confirm the objectivity of dynamic anomalous behavior and show that this behavior may happen under certain circumstances. |
