Finite element modeling of a prototype friction stir welded blank made of aluminum alloy 2024-T351 is considered in this paper. Feasibility of implementation of the experimentally-obtained mechanical properties of the weld nugget and heat-affected zones in FEM models is investigated. Limiting dome height test is considered as case of the study. Three different finite element models implementing different levels of the weld details are built and compared. It is shown that despite increased simulation time, implementation of the weld nugget and heat-affected zones is justified by significantly improved accuracy of the simulation results.
