Miniature-Hopkinson bar technique;

Determination of dynamic behavior of materials at elevated temperatures and high strain rates using Hopkinson bar;

The CFRP and GFRP laminates with a crack on a single side are loaded under tensile impact by the apparatus of Hopkinson bar.

According to the model of the pulse load produced by split Hopkinson pressure bar(SHPB) mechanism,the stress-strain curves were obtained by using ANSYS/LSDYNA finite element method,and the effect of the friction of the interface between the pressure bar and specimen and slenderness ratio of specimen on stress uniformity in specimen were discussed.

The ConeCylinder Projectiles are applied in the split Hopkinson pressure bar experiments.

Design Criterion in Dynamic Fracture Control of Steel Constructions and Design for Hopkinson Pressure Bar;

Dynamic fracture toughness(KId) of 12Cr1MoV steel at various temperatures is tested with Hopkinson pressure bar used to impact specimens and liquefied nitrogen and alcohol used to modulate experimental temperature.

In the present paper,a kind of pneumatically synchronous mechanism is used to the split Hopkinson pressure bar,the technique of high strain-rate loading for a sample at high temperature is introduced.

By using MTS(Mechanical Threshold Stress)model and the experimental technique of the split Hopkinson bar with the synchronization assemblage,the dynamic constitutive equation of the unidirectional-solidified horizontal-continuous-casting polycrystal copper was investigated.

By using MTS (Mechanical Threshold Stress) model and the experimental technique of the split Hopkinson bar with the synchronization assemblage, we determined theoretically the parameters of the dynamic constitutive equation of the continuous casting polycrystal copper.
