High strain rate micro-compression for crystal plasticity constitutive law parameters identification
Materials & Design, 2020 Microcompression tests were performed on single crystal copper micropillars at 10−2 s−1 and 102 s−1 in the [100], [110] and [111] orientations, to provide inputs for crystal plasticity strain rate sensitive parameters inverse identification.

High Strain Rate Compaction of Porous Materials – Experiments and Modelling
EPJ Web of Conferences, 2018 Porosity can be found in many forms in common materials, either naturally occurring such as wood, or introduced by a manufacturing process. Applications for such materials include impact protection and energy absorption, which require a good ...

Modeling strain rate sensitivity and high temperature deformation of Mg-3Al-1Zn alloy
Journal of Magnesium and Alloys, 2019 Increasing the plastic deformation temperature of Mg alloys results in higher strain rate sensitivity, easier activation of secondary slip modes, and impeded twinning. In this study, the strain rate sensitivity is estimated for each deformation mode, and

Dynamics of structural defects and plasticity: models and numerical implementation for dynamical problems [PDF]
, 2013 We report the plasticity model with explicit description of kinetics of the material defects (dislocations, grain boundaries). This method becomes especially effective for computation of the dynamical deformation of materials at high strain rates because

Pressure-strain-rate events in homogeneous turbulent shear flow [PDF]
A detailed study of the intercomponent energy transfer processes by the pressure-strain-rate in homogeneous turbulent shear flow is presented. Probability density functions (pdf's) and contour plots of the rapid and slow pressure-strain-rate show that ...
