OSTI ID:6345902
The model equations described in this paper are able to reproduce the qualitative behavior of the elastic-plastic Rayleigh-Taylor instability response seen in numerical experiments. Both elastic shear modulus and yield strength play important roles in the response characteristics. For low driving pressures a critical amplitude stability criterion may be appropriate. For sustained high pressure this rule will not be sufficient as there will exist wavelengths on the order of the plate thickness.
