Laser shock forming (LSF) is a novel plastic forming process which utilizes a laser-induced shock wave to deform sheet metals to 3D configurations. Quantitative evaluation of the deformation in LSF is of great importance to understand the forming mechanism and achieve the high precision. In this paper, considering parameters of material, geometry and processing, an analytical model was proposed to predict the deformation of plate in laser shock bulging. Models showed that the deformation is related to the impedances of the metal target and the confining overlay, the density, yield strength and thickness of the material, the radius of the die, and the energy, radius and pulse duration of the laser beam. The deformation profiles and the maximum deformation height calculated by the analytical model agree with those of the experiment, which validate the rationality of the constructed models. The maximum deformation height increases with an increase of laser energy, while it decreases with increasing plate thickness.

“…The demand in the market for products with high precision and variety has been growing rapidly, which prompts researchers to develop new forming processes to realize rapid and low-cost forming. Currently, this technique has attracted a lot of attention and is expected to substitute the existing sheet-forming techniques to fabricate the meso/micro parts with complex shapes, since it has lots of advantages, such as fast setup, high flexibility, and repeatability [1][2][3][4].…”

Laser shock forming (LSF) is one of the sheet metal dynamic forming techniques that employ laser-induced shock waves to form sheet metal into complex three-dimensional parts rapidly. This work investigates the effect of sheet thickness on the forming precision in laser shock forming with mold. ABAQUS/Explicit analysis software is adopted to study the effect of sheet metal thickness on forming accuracy. The corresponding forming experiments with sheet thickness arranged from 0.1mm to 0.4 mm are conducted to validate those numerical values. The numerical and experimental results indicate that the sheet thickness plays an important role in the precision of the formed parts, with the increase of sheet thickness, the forming precision is decreased.
