3 terms and definitions
The following terms and definitions apply to this document.
3.1
Elastic longitudinal wave velocity elasticlongitudinalwavevelocity
The Propagation Rate of Elastic Pitch in the Sections of Equal Cross Section.
3.2
Dynamic shock shear stress dynamicpunch-shearstress
The ratio of the shear load to the original shear area of the specimen at any moment during the impact shear process.
3.3
Dynamic shock shear displacement dynamicpunch-sheardisplacement
The difference between the displacement of the end of the input rod and the end face of the output tube in contact with the specimen during the impact shearing process.
3.4
Dynamic impact shear strength dynamicpunch-shearstressstrength
The maximum shear stress of the specimen during dynamic shock shear failure.
4 test principle
Based on the piecewise one-dimensional Hopkinson rod test principle, the striker strikes the input rod at a constant speed, forming an incident elasticity in the input rod
Compresses the stress wave and propagates forward, and loads the sample between the input rod and the output tube dynamically so as to shear the specimen along the thickness direction.
The elastic wave and the reflected wave are measured by the strain gauge on the input rod. The elastic transmission wave is measured by the strain gauge on the output pipe. According to the one-dimensional stress wave
Theory, calculate the dynamic impact shear stress and dynamic impact shear displacement of the specimen. The schematic diagram of the test device is shown in Fig.
