Explosive magnetic liner systems to study dynamic strength of materials

Abstract: 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 … Show more

“…Magnetically imploded cylindrical liners can be used to study dynamic shear strength properties of materials based on the growth of initial perturbations during the RayleighTaylor instability development in liner systems [1][2][3][4][5][6][7]. High-current capacitor banks (Pegasus-2, Shiva Star, Atlas, peak currents I max = 6 y 30 MA) and disc explosive magnetic generators (DEMGs, I max = 20 y 70 MA) are capable of driving cylindrical liner systems to a wide range of material pressures from~1 GPa [2,3] to hundreds of GPa [5].…”

Numerical simulations of the experimental perturbation growth make it possible to test different dynamic strength models [3,7].…”
