Electromagnetically Assisted Stamping -A Vision of a Possible Future for Metal Forming And Progress in Modeling Electromagnetic Sheet Metal Forming

摘要

Sheet metal forming at high velocities has been shown to have several significant advantages over traditional quasi-static sheet metal forming. For example formability is improved and wrinkling can be minimized. This paper does two distinct things in two separate parts. First we describe a vision of how electromagnetically augmented sheet metal forming may solve many current practical problems in metal forming. Second we address one key aspect of this -- the development and validation of numerical models. In particular we show that the GEM code of ARA, is consistent with many experimental observations.
