Abstract
In order to study the effect of laser power density on laser shock formability of aluminum alloy sheet, the forming limit, depth, thickness and stress distribution of the sheet were simulated under different laser power density and different number of laser shock. The results show that fracture is prone to happen in the centre of sheet and the forming limit is inversely proportional to the laser power density,but directly proportional to the number of laser shock. The formability of aluminum alloy sheet can be optimized through proper choice of laser energy and the number of laser shock.
