| Abstract Scope |
Currently, the application of magnesium alloys are growing fast in automotive components because they are 33% lighter than that of aluminum alloys. One of the big obstacles for using magnesium alloys in vehicle structures is joining technique for similar and dissimilar materials. Currently, a front shock tower of passenger vehicle is developed with various magnesium alloys and joining methods. To predict the fatigue behavior of the joints in the structure, fatigue tests of various joints including friction stir linear welding, self-piecing rivet joint with and without adhesive, and friction stir spot welding. Fatigue prediction method based on stress-life curve was used to predict the fatigue life of the various joints in the structure. The finite element modeling technique and the fatigue prediction method were verified with fatigue tests of the actual front shock tower structure subjected to variable amplitude loadings. |
