Determination of The Dynamic Response of Q345 Steel Materials by Using SHPB

摘要：

In this paper a split Hopkinson pressure bar (SHPB) setup was used to test mechanical properties of Q345 steel materials used for industrial structure under high strain rate and high temperature loading conditions such as rocket launching.To provide a consistent and accurate safety assessment to these mechanical structures, the mechanical dynamic response of Q345 steel under high strain rate loading conditions in the same high temperature in different shock times have been developed numerically and experimentally.Special emphasis is placed on determining the experimental relationship between stress and strain compared with different shock times, which is used as a basis for the data analysis procedure. Experimental results for mechanical properties of Q345 steel materials under the extreme conditions from SHPB tests are provided.
