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.

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.

SHPB Experimental Investigation used for Concrete

Advanced Materials Research, 2011
The incident wave and transmission wave varying with the time have been obtained by SHPB experiment. The relationship curve for stress and strain of material concrete has also been obtained. The Weibull function is used to describe the damage factor of the concrete. The damage factor of the concrete changing with the time under the impact conditions is

Temperature in high temperature SHPB experiments

Transactions of Tianjin University, 2008
As an experimental technique, it’s desired that the temperature in specimen is uniform in high temperature split Hopkinson pressure bar (SHPB) experiments. However, the temperature in specimen decreases and the temperature of bars increases when specimen starts to contact with bars, which induces the nonuniform temperature distribution in specimen, and

Numerical modelling of SHPB splitting tests

Journal de Physique IV (Proceedings), 2003
The Splitting or Brazilian test of disks is a useful method to measure tensile strength on brittle materials. When the tensile stress reaches the tensile strength, the disk fails on the loading plane. Nevertheless, the stress state is not uniaxial, and the material undergoes compressive stresses, normal to the tensile ones.

Ø100mm SHPB Equipment and its Application

Applied Mechanics and Materials, 2011
Hopkinson Pressure Bar (HPB) is one of the main sets to study material dynamic mechanic properties. Large diameter HPB is mainly used for nonhomogeneous materials. In this paper the properties of Split Hopkinson Pressure Bar (SHPB) of Ø100mm are introduced, including its structure and performance index.
