Coupled 3D Finite Element Modeling of Electromagnetic Free Expansion of Al Tube [PDF]
International Journal of Advanced Materials Manufacturing and Characterization, 2013 In automotive industry there is a general trend of decreasing the vehicle weight which encourages the use light weight metals like aluminium. As EMF can enhance the formability of aluminium it is becoming popular in automotive industry. The limitations of conventional forming like low formability increased wrinkling and springback can be overcome by ...

Experimental Study and Numerical Simulation of Electromagnetic Tube Expansion
, 2012 Material constitutive models are important to predict deformation behaviour of materials. To identify parameters of constitutive models for high-strain-rate forming, appropriate methods are needed to investigate the dynamic behaviour of materials. Electromagnetic forming is a high-velocity and high-strain-rate forming process in which velocities of up ...
