The dynamic buckling of the implosion liners driven by magnetic pressure has been investigated experimentally and numerically. The study of the effect of material properties and dimensions and loading currents on liner buckling, using a capacitor bank as a driver, indicates that the mode number for buckling increases with the ratio of radius to thickness of a liner, and the yield strength to plastic hardening modulus, but keeps invariable with the increase of loading current, and that the magnitude of buckling increases with the loading current. The numerical simulation to the experimental results by an instant non-linear finite element method, shows basically an agreement between them.
