Abstract: In this manuscript, the main objective is to develop a numerical study, based on the finite element method, to create a wrinkling tube in aluminium. The technique applies to an electric potential imposed on the tube mesh, which goes within a solid die with cavities to achieve the wrinkling process, using contact elements. A nonlinear material with lateral incremental voltage electric potential, due to an electric coil, and employed vertical displacement was used in an axisymmetric numerical model. The results were analysed, which allowed the tube deformation to be obtained, with a large lateral displacement, as with the previous experimental results. The deformation patterns and the magnitude of lateral displacement are influenced by tube geometry, material properties, and loading conditions. This method leverages the synergy between electric potential, die cavity design, and precise contact modelling to induce and control wrinkling in tubes, with the finite element method providing a robust framework for process simulation and optimisation.
