Summary:
There has been a lot of research on fracture/failure of different welding joints in tensile and impact load conditions and research attempt to make better properties welding joint. However, Al and Mg alloys dissimilar joint [for weight reduction in automotive, aviation and aerospace (AAA) industries] has not been studied yet in this regard. The aim of this research was to carry out mechanical tests and analysis, finite element analysis (FEA) or numerical simulations; and validate the FEA results by comparing with experimental results for the fracture prediction of such joint (to predict the failure location, and on what tensile and impact loading conditions the joint fails). This research can establish the acceptability of Al and Mg alloys compound light weight vehicle structure/body in AAA industries for the purpose of fuel efficiency and recyclability; for safe design and production of such structure/body in crash conditions to tackle fatalities.
