Abstract

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.
