|Title:||Simulation of Wrinkle Formation in Free Electromagnetic Tube Compression|
|Abstract:||A 3-dimensional (3D) finite element (FE) simulation of free electromagnetic (EM) tube compression was performed with the aim of predicting wrinkle formation. Staggered coupling was applied between the EM and mechanical parts of the problem. The full 360° portion of the problem was modelled since the wrinkle formation does not represent any symmetry in circumferential direction. The initial geometric imperfections of the tube were measured and included in the model to trigger buckling. The deformed geometry with the wrinkles could be predicted accurately.|
