Numerical Simulation of SHPB Experiment and Analysis on Stress Wave

Applied Mechanics and Materials, 2011
Concrete is a typical kind of rate sensitive material. In this paper, the concrete specimens were tested in the SHPB experiment system. Based on H-J-C constitutive model, the SHPB experiment was simulated by LS-DANY. The stress-strain curves which were gat from numerical simulation in the LS-DANY were compared with the stress-strain curves which were ...

On the errors associated with the use of large diameter SHPB, correction for radially non-uniform distribution of stress and particle velocity in SHPB testing

International Journal of Impact Engineering, 2006
The large diameter (up to 100 mm) Split Hopkinson Pressure Bar (SHPB) setup is used throughout the world to test large-cell heterogeneous materials, small structures, etc. This paper proposes a correction method to take into account the non-uniform distribution of stress and particle velocity (non-plane wave effect) in large diameter setups, following ...

A modified method of pulse-shaper technique applied in SHPB

Composites Part B: Engineering, 2019
Abstract During the experimental measurement of solid materials by SHPB, a pulse-shaper technique is used to eliminate high-frequency oscillation components and acquire an incident pulse with a rising time that is greater than the time needed by the test specimen to reach a stress equilibrium state.

Experimental study for friction effect investigation on SHPB

, 2001
The paper presents an investigation on SHPB behaviour used for material characterisation in compression testing at high strain rate. Material flow stress determined with the SHPB test is affected by radial and axial inertia as well as friction. The particular topics treated are the effects of friction between specimen and bars interfaces on the flow ...

Strain-rate effect of polymers and correction methodology in a SHPB test

International Journal of Impact Engineering, 2022
Split Hopkinson pressure bar (SHPB) has been commonly used to characterize the dynamic behavior of polymer at high strain-rates from 102 to 104 s−1. Based on numerical SHPB tests and Drucker-Prager model, this study examines the SHPB technique for the ...

CORRECTION OF LATERAL INERTIA EFFECT IN SHPB

International Journal of Modern Physics B, 2008
A theoretical analysis of the stress state in specimen of the SHPB experiment was performed in consideration of lateral inertia effect. The nonuniformity of lateral stress in specimen and variety of deforming velocity in the loading process were taken into account in the analysis. A formula to correcting the lateral inertia effect was obtained.

Strain rate design in SHPB test

SPIE Proceedings, 2009
A strain rate calculation formula of split Hopkinson pressure bar (SHPB) test is derived from one-dimensional stress wave propagation theory. According to the test conditions and specimen size, the test strain rate can be calculated by the formula; and the strain rate limitative range of SHPB test is analyzed.
