Anew set-up is proposed to perform high strain rate tension experiments on sheet metal using a compression Hopkinson bar system on the input side.With the help of a custommade load inversion device, the compression loading pulse is converted into tensile loading of the specimen boundary. A tensile output bar is used to measure the tensile force acting on the specimen boundaries. A high speed ca...

Investigations on rock dynamics have been comprehensively focused when the dynamic impact is perpendicular to trend of flaws, while understanding mechanical properties and failure characteristics with pre-flaws parallel loading direction remains unrevealed. In this study, tests are performed experimentally study properties, characteristics, energy evolution pre-flawed sandstone using split Hopk...

Abstract In this study, the mechanical response of HTPB propellant grain under ultra-high loads is investigated. The low, intermediate and high strain rate uniaxial compression tastings (1.7×10 −4 ~3×10 3 s −1 ) hydroxyl terminated polybutadiene (HTPB) at room temperature were carried out by using universal testing machine split Hopkinson pressure bar (SHPB) system, respectively. tests cellular...

Compared with polyvinyl alcohol-engineered cementitious composites (PVA-ECC), engineered containing polyethylene fibers (PE-ECC) has captured the attention of researchers because lower cost. Nevertheless, there is a limited amount research that focuses on their dynamic behavior. Thus, specimens different water binder ratios were tested by split Hopkinson pressure bar (SHPB) to unveil compressiv...

The dynamic uniaxial impact compression test was carried out by the Hopkinson pressure bar system to mechanical properties of concrete with different fly ash contents ( P = 0 , 10%, 20%, 30%, 40%, and 50%) under 0.3 MPa air pressure. influences content variation on characteristics, ductility characteris...
