Abstract: The cylindrical liner motion at the action of electromagnetic forces is discussed. A set of calculations was carried out for modeling the motion of liner central part (without the influence of the supports). Another series of calculations was carried out for modeling the liner motion near the supports. The comparison of integral characteristics and liner profiles for elasto-plastic model and incompressible liquid model was executed. The influence of deformation curves and values of dynamic viscosity coefficient for liner motion characteristics was investigated. Results of a full-scale experiment on compression of a long thin-walled the liner with a diameter of 90 mm with pulse 6 MA current were shown.
Keywords: cylindrical liner, large deformation, incompressible liquid, tensor of logarithmic strain.
