Quasi-Static and Impact Strength of Fatigue Damaged Spot Welds 2003-01-0610

As the automotive industry becomes more concerned with the crash performance of automobiles, the behavior of used vehicles becomes an interesting subject. In this work, the effect of aging on spot welded joints was simulated by applying fatigue loading to the samples. Samples were then subjected to quasi-static and impact tests to measure the effect of fatigue aging to the strength of the samples. The results show (a) a reduction in the strength of the test samples under impact conditions, (b) no obvious reduction in quasi-static conditions, and (c) significant reduction in strength if cracks in the welds were initiated during the fatigue aging process.
