Abstract: By utilizing the ABAQUS software, this paper simulates and analyzes the forming of the H62 foil subjected to multi-pulse laser dynamic forming (LDF). The Johnson–Cook failure mode is adopted to predict the fracture threshold value of the H62 foil. Compared with the single-pulsed LDF, the multi-pulsed LDF improves the limit depth and forming quality of the foil effectively. With the increase of impact number, the uniformity of foil is effectively improved. Appropriate peak pressure and impact number are important to increase limit forming depth and improve forming quality.
