A finite element study of electromagnetic riveting

Electromagnetic riveting, used in some aerospace assembly processes, involv es rapid deformation, leading to the finished rivet configuration. Analysis of this process is described for the case of an aluminum rivet joining typ ical aluminum structural elements. The analysis is based on a finite elemen t method that includes the effects of heating, due to rapid plastic deforma tion of the material, on the material properties. Useful details of materia l deformation and thermal history and the final rivet and structure configu ration ann states of stress and strain are obtained These results have sign ificant implications in the design, implementation, and improvement of prac tical fastening processes in the aerospace industry.
