<p>A combination of simulation and experiment was employed to investigate the coordinated forming process, focusing on the forming ability and symmetry, of the integral stiffened structure (ISS) in both the UD and CD by laser peening (LP). The dynamic response process and forming ability of the ISS were systematically explored under various forming and scanning strategies. A comprehensive comparison and analysis of the stress evolution process and distribution state were conducted, identifying and harmonizing the optimal process strategy in the both directions. The coordinated forming process strategy for the ISS was validated through experimental means. The results reveal that “plate driving stiffener” forming strategy offers larger forming ability in the UD, whereas “stiffener driving plate” strategy exhibits increased forming ability in the CD. The deformation value achieved through “sequential forming” in the UD is maximum, while “symmetric interleaving forming” proves to be the most effective forming strategy in the CD. The forming strategy of “plate driving stiffener” demonstrates significant beneficial compressive stresses on both sides. The “sequential forming” scanning strategy results in a more uniform distribution of compressive stress, thereby enhancing material durability more effectively. By integrating the optimal process strategy, the curvature radius is 566.3 and 162.5&#xa0;mm in the two directions, demonstrating a significant enhancement in forming ability.</p> Graphical Abstract <p></p>
