Dynamic analysis of multilayered welded aluminum cantilever beams

Welded joints are often used to fabricate assembled structures in machine tools, automotive and many such industries requiring high damping. Vibration suppression in these applications can enhance the dynamic stability significantly. A little amount of work has been reported till date on the damping capacity of welded aluminum structures. The present work outlines the basic formulation for the slip damping mechanism in multilayered and tack welded aluminum beams, vibrating under dynamic conditions. It is observed that there are a number of vital parameters that govern the damping capacity of these structures. The developed damping model is found to be fairly in good agreement with experimental results.
