Research on Mechanical Properties of Q345 Steel Impacted on High Temperature and Dynamic Shock Load
Aiming at the reliability of Q345 steel material impacted on high temperature and dynamic shock load, its mechanical properties are studied in this paper based on the split Hopkinson pressure bar, the SHPB test facility is introduced in detail. And the stress-strain curves of Q345 steel are obtained in the special industrial condition. The flow stress decreases clearly in pace with the increasing of temperature, which provides credible technique evidences for the maintenance and health appraising of the structure.
