Tamped Richtmyer-Meshkov instability behavior under non-shock loading

The Richtmyer-Meshkov instability (RMI) occurs when a shock intersects an interface between materials of differing densities, causing perturbations at the interface to grow. However, the RMI can also occur under non-shock loading as we explore here. Non-shock loading is less efficient at growing the...

Description
Summary:The Richtmyer-Meshkov instability (RMI) occurs when a shock intersects an interface between materials of differing densities, causing perturbations at the interface to grow. However, the RMI can also occur under non-shock loading as we explore here. Non-shock loading is less efficient at growing the RMI because of the evolution of perturbations at the interface during the loading process. Non-shock loading also results in significantly less dissipative heating, suggesting that non-shock RMI could be used to investigate thermal aspects of strength in the high-pressure, high-strain rate regime.
