The method of metal foil forming under laser-driven flyer loading was introduced and the speed of flyer was calculated through Gurney model. The 10 μm thickness aluminum flyer reached a speed of 250 m/s when laser power density was 0.64 GW/cm2. The impact pressure went up to 1.9 GPa which was about 3 times of laser induced at constraint model. It was shown that laser driven flyer loading had higher forming ability than laser shock. The micro-forming process of metal foil under laser-driven flyer loading was simulated by LS-DYNA. The flyer stress and speed was studied, the simulation results agreed well with theoretical calculations. And the mechanism of laser driven flyer loading was verified.
