Modeling the forming process by successive local deforming for monolithic stiffened panels

The study considers a method for forming stiffened monolithic panels by local deformation of the panel ribs. is caused bending moments along rib towards each other. goal to numerically model process utilizing designed local-impact tool and analyze its effects on panel, obtaining which experimentally challenging. finite element (FEM) modeling performed in ANSYS validated experimental made an aluminum alloy analogous Al 2024. Simulation results provide deformation, stress, strain distributions loaded unloaded states various cases. Furthermore, length, width, parameters such as applied force couples single versus successive are investigated discussed. Performed demonstrates advantages with terms low residual stresses their distribution. Finally, analysis suggests future modification tool, particularly shape grips, minimize stress concentrations.
