Results and Prospects of Material Strength Studies on Electrophysical Facilities Based on Perturbation Growth in Liner Systems

Data are presented describing refined simulations of perturbation growth in a three-layer cylindrical liner system tested with disk explosive magnetic flux compression generators (DEMGs) to study the strength properties of copper and polyethylene at shocklessly applied pressures of up to ~15 GPa. The calculated performance for the same liner system in the experiments to study the strength properties of copper at shockless loading of up to ~40-GPa pressures is presented. The feasibility of similar strength experiments with quasi-isentropic material compression to ~2000 GPa using DEMGs is demonstrated.
