This problem is of particular interest to the hydrodynamic stability of the LAPLAS target [2] because the payload (cold flyer around the sample) remains in solid state and therefore it retains its material properties including yield strength which has a stabilizing effect on the target implosion. It is also important to note that no selfconsistent theory of RM instability exists, specially in the non–linear regime. One can therefore carry out dedicated experiments at the FAIR to study the problem of the RM instability in linear as well as non–linear regime.

Evaluation of the Dynamic Yield Strength of Solids by Means of the Richtmyer-Meshkov Instability
An experimental procedure to evaluate the dynamic yield strength of solids based on measuring the growth of the Richtmyer-Meshkov instability is proposed. To induce the Richtmyer-Meshkov instability in solids a shock is needed, so this technique is complementary to the one based on the Rayleigh-Taylor instability that is achieved by means of an isentropic compression. We have presented an analy...
متن کاملRichtmyer-Meshkov instability in elastic-plastic media.
An analytical model for the linear Richtmyer-Meshkov instability in solids under conditions of high-energy density is presented, in order to describe the evolution of small perturbations at the solid-vacuum interface. The model shows that plasticity determines the maximum perturbation amplitude and provides simple scaling laws for it as well as for the time when it is reached. After the maximum...
متن کاملStudies of Richtmyer–Meshkov Instability Growth in Solids Using Intense Heavy Ion Beams at FAIR / HEDgeHOB
In this contribution we present numerical simulations of the Richtmyer–Meshkov (RM) instability growth in solids, using a plane shock driven by an intense ion beam. The plane shock is generated using the Mach reflection technique [1]. Fig. 1 shows the position of the shock front at t = 500 ns that is propagating from the right to the left. It is seen that the shock is close to the Cu–Al boundar...

An Analytical Nonlinear Theory of Richtmyer- Meshkov Instability
Richtmyer-Meshkov instability is a fingering instability which occurs at a material interface accelerated by a shock wave. We present an analytic, explicit prediction for the growth rate of the unstable interface. The theoretical prediction agrees, for the first time, with the experimental data on air-SF6, and is in remarkable agreement with the results of recent full non-linear numerical simul...
