A NOTE ON DATA PROCESSING IN THE SPLIT HOPKINSON PRESSURE BAR TESTS [PDF]
Experimental Techniques, 1998 In this paper, a close-form relationship between the incident wave and the transmitted wave was deduced on the analysis of elastic wave propagation in SHPB tests for the elastic specimen. The relationship was applied to determine the time delay in data processing of SHPB tests in order to improve the accuracy of the measured stress-strain curve in the ...

High strain rate tensile testing of sheet materials using three Hopkinson pressure bars
EPJ Web of Conferences, 2012 In an attempt to circumvent the inherent problems associated with Split Hopkinson Tensile Bar (SHTB) systems, a new experimental technique is proposed for the high strain rate tensile testing of sheet specimens in Split Hopkinson Pressure Bar (SHPB ...

Identification of non-homogeneous stress fields in dynamic experiments with a non parametric method [PDF]
, 2010 International audienceStress and strain fields are generally assumed homogeneous in high strain rate experiments. Therefore, only mean stress and strain are measured. However, this assumption is not valid for soft materials and/or very high strain rates.

Impact Behavior of Recycled Aggregate Concrete Based on Split Hopkinson Pressure Bar Tests
Advances in Materials Science and Engineering, 2013 This paper presents the experimental results of recycled aggregate concrete (RAC) specimens prepared with five different amounts of recycled coarse aggregate (RCA) (i.e., 0, 25%, 50%, 75%, and 100%) subjected to impact loading based on split Hopkinson ...

Effects of porosity on dynamic indentation resistance of silica nanofoam. [PDF]
, 2017 The dynamic indentation behaviors of monolithic silica nanofoams of various porosities are investigated. When the pore size is on the nm scale, as the porosity increases, despite the decrease in mass density, the resistance offered by silica nanofoam to ...

Numerical Simulation for Bar Straightness Effect in Split Hopkinson Pressure Bar
Procedia Engineering, 2017 Abstract Bars alignment in a Split Hopkinson Pressure Bar influences the quality of signal recorded during experiments, and thus affects the data of material properties being measured. There are some parameters directly related to the bars alignment such as their straightness, the impact face parallelism, and the neutral axis offset.
