This study demonstrates the feasibility of electropulsing-induced fatigue crack closure in aerospace metallic materials. By combining multiphysics simulations and experiments, key process parameters governing crack closure were identified. The results suggest electropulsing as a promising, non-destructive crack management approach applicable to aerospace structures and other safety-critical metallic components.
