在标准冲击试样静态三点弯曲试验中，试样与支座之间保持接触，自始至终为三点受力状态。但在运用Hopkinson压杆进行动态试验条件下，由于加载速率较高，试样可能弹离支座，出现脱离现象。因此，试样有可能偏离三点弯曲状态。但是，目前对试样与支座脱离接触的现象与规律的认识尚不统一。本文通过在支座上粘贴半导体应变片的方法，监测试样与支座开始受力时刻。比较发现，试样在受载瞬间并非处于三点受力状态，确实存在与支座间的脱离现象。并由试验得出不同跨距条件下发生脱离的临界条件。
Static shock in the standard three-point bending test specimen, the specimen and the bearing between the contact force from start to finish for the three states. However, in the use of Hopkinson pressure bar dynamic test conditions, due to the higher loading rate, the specimen may ricochet off the bearings, emerging from the phenomenon. Therefore, the sample may deviate from the three-point bending condition. However, at present on the specimen and supports disengagement phenomena and understanding of the law is not yet uniform. This paper supports the paste through the method of the semiconductor strain gauges to monitor the sample and the bearing force moment of the beginning. Comparison, the sample contained in the subject is not an instant force in the three states,

Comparison, the sample contained in the subject is not an instant force in the three states, and supports the existence of the phenomenon of inter-out. By the pilot arrived at a different place from the span of under the conditions of the critical condition.
