Dispersion Correction for Split-Hopkinson Pressure Bar Data
1988Abstract : Large diameter Split-Hopkinson Pressure Bar (SHPB) systems required a correction of the strain signals to account for wave dispersion. Using a Fast Fourier transform (FFT) algorithm a wave dispersion correction program was developed for the 3.0 inch diameter SHPB at the University of Florida and the 2. 0 inch diameter SHPB at Tyndall AFB FL.

Examination of Validity for Viscoelastic Split Hopkinson Pressure Bar Method
2011The examination of the accuracy for a split Hopkinson pressure bar method with viscoelastic input and output bars (viscoelastic SHPB method), which is one of the methods of evaluating the dynamic properties for viscoelstic materials, is executed. The key-point for accurately determining the dynamic properties of low impedance materials lies in how to ...

Dynamic testing by split Hopkinson pressure bars (SHPB)
2010In recent days there are lots of engineering applications, the design of armor system, highspeed transportation vehicles, aerospace industry, nuclear power plants and high-speed machinery, where materials are subjected to high strain loading. Therefore a comprehensive understanding of behaviour of materials under high strain rate loading is essential ...

Split Hopkinson pressure bar experiment simulation using MUNROU
2013The next generation of 3D combined finite-discrete element method (FDEM) capabilities has been developed at Los Alamos National Laboratory (LANL). These include state of the art contact detection, contact interaction, LANL’s constitutive material, and fracture models all combined in a grand scale parallel computing framework called MUNROU.

Experimental and numerical investigations on split Hopkinson pressure bar
2010Split Hopkinson Pressure Bar (SHPB) has become a frequently used technique for measuring an uniaxial compressive stress-strain relationship of various engineering materials under high strain rates, the pulse shape is sensitive to the length of striker bar.
