New Open Access Publication

Another technical article from the Institute of Manufacturing Technology has been published in the Journal of Advanced Joining Processes. The publication covers the numerical design and analysis of a wobble joining process for dissimilar materials.

This study investigates an approach in which wobble is not only used for forming through the creation of local material accumulations, but also simultaneously generates a mechanical joint in the sheet plane between aluminum and steel. The core of the work is the development and experimental validation of a three-dimensional finite element (FE) model that depicts the material flow as well as the resulting stress and strain states. Based on this model, it is shown that the positioning of the joints in relation to the locally thickened areas significantly influences the joint filling and thus the joint quality. The results provide important insights for the reliable design of hybrid lightweight components.
