How Does the Dynamic Strength of a Material Affect the Velocity of Particles at a Perturbed Shock Front and Can This Be Used to Estimate Dynamic Strength in Solids?

Security icon, disabled. A blue padlock, locked.
The objective of this work is to investigate the relationship between the temporal evolution of particle velocity at different locations of a perturbed (rippled) shock front and the dynamic strength of the material by performing careful experimental measurements in samples carefully designed to produce perturbed shock fronts and comparing them to predictions from direct numerical simulations of the experiment. The findings of this research will further our understanding of dynamic strength effects on the evolution of hydrodynamic instabilities in solids and provide the basis for a potential new technique to evaluate dynamic strength of solids under extreme loading conditions.
