we derived the dispersion relation for the RTI problem at cylindrical fluid/fluid, solid/solid and fluid/solid interfaces by the decomposition method and also its planar counterpart, which is still easily expanded to study the behaviors of the interfaces by the impulsively accelerated model. Searching for the mathematical details of the dispersion relation, we developed a methodology to study...

The linear theory of the incompressible Rayleigh-Taylor instability in elastic-plastic solid slabs is developed on the basis of the simplest constitutive model consisting in a linear elastic (Hookean) initial stage followed by a rigid-plastic phase. The slab is under the action of a constant acceleration and it overlays a very thick ideal fluid. The boundaries of stability and plastic flow are...

Transition of molecular hydrogen to atomic ionized state with increase of temperature and pressure poses still unresolved problems for experimental methods and theory. Here we analyze the dynamics of this transition and show its nonequilibrium non-adiabatic character overlooked in both interpreting experimental data and in theoretical models. The non-adiabatic mechanism explains the strong...
