If it is desired to obtain high rate mechanical data of materials at non-ambient temperatures
using the split Hopkinson (Kolsky) bar technique, it is necessary either to consider what …

Recent advances in additive manufacturing have enabled the construction of metallic lattice
structures with tailored mechanical and functional properties. One potential application of …

Abstract A Photon Doppler Velocimetry system that measures the propagation of elastic
shear waves in a Torsion Hopkinson Bar (THB) system is presented. The method uses …

In uni-axial compression at strain rates above 10 4 s− 1, FCC metals exhibit a rapid increase
in strength. Mechanisms proposed to be responsible for this transition can be broadly split …

Background Measuring the dynamic behavior of low-impedance materials such as foams is
challenging. Their low acoustic impedance means that sensitive force measurement is …

Cobalt Chrome is used extensively within the biomedical industry for hip, knee and shoulder
prostheses. These components are manufactured using a range of different processes …

A process of calibrating a one-dimensional sound speed (co) and Poisson's ratio (ν) of a
(split) Hopkinson bar is presented. This process consists of Fourier synthesis and iterative …

Plastic deformation is a fundamentally important physical process, ultimately determining
how materials can be used. Metal plasticity is governed by dislocation dynamics and lattice …

Conventional Split Hopkinson Pressure Bars (SHPB) or “Kolsky” bars are often used for
determining the high-rate compressive yield and failure strength of materials. However, for …

The mechanical response of the body centred cubic metal vanadium has been studied
across a wide range of strain-rates through uniaxial stress compression. Samples of …
