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.

Study of Stress Wave Propagation in SHPB with NHDMOC

Applied Mechanics and Materials, 2013
In this paper the NHDMOC method which succeeded in studying stress wave propagation with one dimensional strain was applied to study the one-dimensional stress wave propagation. In this paper, the ZWT nonlinear visco-elastic constitutive relationship with 7 parameters to NHDMOC, and corresponding equations were deduced The equations was verified from ...

Enhancing performances of SHPB for determination of flow curves

CIRP Annals, 2001
Abstract A compression test on a Split Hopkinson Pressure Bar (SHPB) is the most common testing method adopted to determine material flow curves in a quite wide range of high strain rates. However, in most ordinary SHPB applications material rheology can only be investigated up to a rather low strain.

Investigation of the effects of transverse inertia on SHPB experiments

International Journal of Microstructure and Materials Properties, 2016
Due to the Poisson's effect, the effects of transverse inertia in specimen tested on Split Hopkinson Pressure Bar device are induced. Transverse inertia has been recognised as an important factor in dynamic responses of brittle materials. Contact friction generated at interfaces of the specimen and two pressure bars, can confine the dilation in the ...

STUDY OF SMALL DIMENSION SPECIMENS ON SHPB TEST

AIP Conference Proceedings, 2008
The feasibility and reliability of small dimension specimen SHPB tests were investigated by numerical simulation and experiments of 2024 aluminium alloy with series of dimension. Also an attempt is made to get curves of strain rate over 104 s−1 by small dimension specimens. Accuracy of transmitted signal in eccentric compression tests of small specimen

Simulating Wave Propagation in SHPB with Peridynamics

2013
Split Hopkinson’s pressure bar (SHPB) is commonly used for characterizing materials at high strain rates. In obtaining an admissible stress–strain curve at a specific strain rate, force equilibrium through the specimen is required. Due to the blunt collision between the striker bar and the incidence bar in SHPB, a strain wave with a blunt wave front is

Dynamic deformation behavior of bovine femur using SHPB

Journal of Mechanical Science and Technology, 2011
This paper investigates the dynamic deformation behavior of bovine femur using a modified split Hopkinson pressure bar (SHPB) with a pulse shaper technique. The shape of the incident and reflected pulses modulated by the pulse shaper were measured and compared to each other to find a suitable thickness.

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 ...
