Investigation in Friction Stir Welded Aluminum Alloy 2139-T8 for Hull Structure Applications

Abstract

2139-T8 aluminum and the use of FSW for joining of the material is understood from a quasi-static and dynamic response, however if the material is going to be used in an integrated hull structure, additional understanding is needed related to material fatigue. Military vehicles perform in very rigorous environments and use conditions. The hull structure is exposed to many different loads and cycles during its use life. This report summarizes the experimental testing and Stress-Life (S-N) curve development for 2139-T8 aluminum and FSW 2139-T8 aluminum.
