High Strain-Rate Compression Tests on Ice

The Journal of Physical Chemistry B, 1997
High-speed uniaxial compression tests were conducted in the strain-rate range 10-1−101 s-1, at −11 °C, on freshwater ice and “Baltic” sea ice of mean salinity 2.4 ± 0.7 ppt.

Large Strain, High Strain Rate Testing of Copper

Journal of Engineering Materials and Technology, 1980
This paper describes the development of a high-speed torsional testing machine and results obtained on the strain-rate dependent strength of copper at large shear strains. Test techniques and data obtained are intended to be useful in applications such as ballistics and machining.

High-Strain-Rate Loading

2014
The disk-shaped composite specimens with different compositions of MWCNTs were then subjected to high-strain-rate impact, and their dynamic impact loading behavior results were compared with variations in compositions of MWCNTs.

Stress-Strain Properties of Plastics at High Strain Rates

Review of Scientific Instruments, 1966
Apparatus of the falling weight type previously developed for tensile testing of rubbers at strain rates up to 14.5 m/sec has been made stiffer and more sensitive to accommodate plastics. Loads up to 225 kg and resolution to about 50 μsec have been achieved using a piezoelectric transducer.

Strength of Metals and Alloys at High Strains and Strain Rates

1977
The effects of strain rate and strain-rate history on the strength of metals at high strains have been investigated in two series of tests at room temperature using the split Hopkinson-bar method to obtain shear strain rates up to 3000 s-1. In the first series, various materials were subjected to nearly constant low and high strain rates in torsion ...

High strain rate response of an elastomer

High Pressure Research, 1992
Abstract Plate impact experiments have been performed to examine the high strain rate response of an elastomer (explosive binder) shocked to 8 kbar stress. Particle velocity data have been obtained using in-material electromagnetic velocity gauges. Normal impact experiments have provided compression and release wave velocities and stress-strain results;

High rate straining of tantalum and copper

Journal of Physics D: Applied Physics, 2010
High strain rate measurements reported recently for several tantalum and copper crystal/polycrystal materials are shown to follow dislocation mechanics-based constitutive relations, first at lower strain rates, for dislocation velocity control of the imposed plastic deformations and, then at higher rates, transitioning to nano-scale dislocation ...

Strain Rate History Effects and Dislocation Substructure at High Strain Rates

1983
A brief review is presented of strain rate history and temperature history effects during the high strain rate deformation of metals with special emphasis on the BCC metals. Possible explanations to account for history effects are reviewed. Experiments are described in which single crystals of aluminum are deformed at various strain rates. Observations
