Abstract Scope |
The drag effect on material strength, influenced by both viscous and phonon drag, plays a significant role in determining the mechanical properties of materials, especially at the microscopic level. Applying RMI tests on solids involves generating shock waves that pass through material interfaces, creating instabilities that can provide valuable insights into the dynamic behavior of materials in these regimes. As well the DTE test, such tests can help understand the materials’ response to high-strain-rate deformations while avoiding the problem of friction during the extrusion of the material into the die. Line perturbations of microns were machined to generate the spikes, simplify the specimen preparation, measure the velocity of a single spike, and generate a material jet comparable in size to that obtained in DTE; a larger axisymmetric perturbation was machined. The fragments were recovered, and the microstructure was analyzed and compared to the DTE findings to ensure accuracy and reliability. |
