High Strain Rate Properties of High Strength Steel Sheets
International Journal of Automotive Engineering, 2011 High strain rate properties of sheet steel largely depend on its strength level and strengthening mechanisms. The strain rate sensitivity of flow stress has a close relation with the hardness of a softer phase, which indicates superior strain rate ...

Discontinuous Yielding of Fe E420 under High Strain Rate Loading
Applied Sciences, 2023 The discontinuous yielding behaviour of Fe E420 steel was experimentally investigated through tensile tests conducted on laminated sheets. In order to assess the response under both quasi-static and dynamic loading conditions, uniaxial tensile tests were

High strain rate behaviour of polypropylene microfoams
EPJ Web of Conferences, 2012 Microcellular materials such as polypropylene foams are often used in protective applications and passive safety for packaging (electronic components, aeronautical structures, food, etc.) or personal safety (helmets, knee-pads, etc.).

High strain rate response of UHP(FR)C in compression
EPJ Web of Conferences, 2015 The objective of this study was to investigate the compression behaviour of the UHPFRC and its matrix (UHPC) under high strain rate. Two experimental set-ups were used for compression testing: a traditional Split Hopkinson Pressure Bars and a compression

High strain rate deformation of layered nanocomposites [PDF]
Nature Communications, 2012 Insight into the mechanical behaviour of nanomaterials under the extreme condition of very high deformation rates and to very large strains is needed to provide improved understanding for the development of new protective materials. Applications include protection against bullets for body armour, micrometeorites for satellites, and high-speed particle ...

Dislocation Damping in Aluminum at High Strain Rates [PDF]
Journal of Applied Physics, 1967 Impact shear tests of the Kolsky thin-wafer type were used to determine the effect of temperature and strain rate on the critical resolved shear stress for slip in aluminum single crystals at strain rates of 104 sec−1 and in the temperature range 20° to 500°K.
