Revisiting hotspot ignition and growth due to pore collapse and shear localization using atomistics-consistent material models
The calculation of hotspot ignition and growth rates is crucial to providing closure in the form of burn models to hydrocodes that predict the shock-to-detonation transition in energetic materials. Pr...
Strength softening in copper upon compression: Competition between Hall–Petch and dislocation density effect
The strength enhancement of materials under modest loading was first documented by Bridgman, nearly a century ago. However, specific materials present anomalous strength softening at high pressures, i...
Self-ordering of metallic surfaces in the trampoline structuring regime
Surfaces of some metals (copper and aluminum) and alloys (black and chromium–nickel stainless steels) were irradiated with argon ion-plasma flows under the trampoline mode conditions, i.e., at high io...
