Abstract
The present disclosure provides a dynamic true triaxial electromagnetic Hopkinson bar system and testing method, the method including: firstly, before applying a static prestress and an impact load, recording and storing complete ultrasonic signals in the directions X, Y, and Z without application of the static prestress and the impact load; secondly, applying the static prestress; thirdly, recording and storing complete ultrasonic signals in the directions X, Y, and Z under the static prestress; fourthly, applying the impact load, and utilizing an triaxial and six-directional synchronous-coordinated-control electromagnetic loading system to apply a dynamic impact load to a test specimen; and fifthly, after completing the dynamic impact loading test, recording and storing once again complete ultrasonic signals in the directions X, Y, and Z without releasing the static prestress after application of the static prestress and the dynamic impact load.
