Description
Summary:	Electromagnetic welding is an innovative, high-speed technology to manufacture mixed material joints. In this dissertation, an experimental-numerical method is presented to identify robust process windows of aluminum-copper and aluminum-steel compounds. The microstructural characteristics of these joints were investigated in detail. Moreover, an evaluation of the joint quality is presented and different numerical models were introduced for the simulation of macroscopic and microscopic effects. To improve the accuracy of the simulations, the strain rate sensitivity of the materials must be considered. For this purpose a high-speed setup for the identification of relevant viscoplastic material parameters, comprising an inverse evaluation strategy, was developed.
