Numerical Modeling of High-Speed Free Bulging of Thin-Wall Aluminum Tubes under the Action of Impulse Electromagnetic Forces

Abstract

The paper proposes an approach in numerical modeling of electromagnetic forming of aluminum tubes. The investigated technology refers to a free expansion/bulging, without a die, of a thin wall aluminum tube. The aim is to build an accurate model that can take into account the particularities of the process, which is useful for numerical investigations regarding an optimal design of the device.
