Finite element modeling and experiment for behavior estimation of AlMn0.5Mg0.5 sheet during electromagnetic forming

The electromagnetic forming is a procedure of high-speed processing, which favors the increase of the formability of some plastically deformed metals. In order to evaluate the capacity of some light metals, such as aluminum and its alloys, to be deformed through this procedure, it is useful to know the stress and strain state that occurs in the material during forming. In this work, the modeling of stresses and strains in electromagnetically deformed AlMn0.5Mg0.5 sheet was made. The modeling was achieved using the finite element method and it was verified through experimental tests. To determine the residual stresses, the X-ray diffraction method was used. The strains were established by measuring the displacements of the nodes in the network inscribed on the specimen by means of three coordinates measuring machine. A good agreement between the modeling results and experimental data was found.
