AbstracfTo study dynamic strength of materials according to the initial liner perturbation'growth in Rayleigh-Taylor insta-bility development, three-layer liner systems driven by azimuthal magnetic field pressure have been suggested. This paper demodtrates that 0.4-m-diameter disk EMG ensuring currents up to -70 MA can be used for this pur-pose. In the three-layer liner systems, the liner shock-free loading to more than 1 Mbar pressures is therewith possi-ble, with the pressures rising for times longer than 1 ps or longer than 0.3 ps in different systems. Here the shock loading of the liners under study is possible up to 3 -4 Mbar pressures.Examples of 2D computations of the initial perturbation growth in the liners under study at shockfree and shock pressures up to 1 Mbar, strain rates up to 10' sec-', and strains up to 200 % are given.
