摘要: Abstract The main aim of the present work is to develop a cellular automata coupled finite element (CAFE) model predict grain size distribution during friction stir welding (FSW) and influence weld defects (like voids) on forming FSW sheets. In order achieve this, process simulated just by applying thermal strain-rate analytical models elements constituting blanks using ABAQUS6.8 (FE) code with help DFLUX sub-routine. A uniform grid mesh within each for accommodate generated calculation. sheet used Al6061-T6 dimension 300 × 100 × 2.1 mm. final yield strength are predicted generating transition rules, relating them temperature, strain evolved welding. computed results compared experimental validation. (true stress–strain) behavior was containing two different methods their accuracy compared. followed in this temperature across region consistently. matching well available data. predictions through CAFE agreeing all conditions. true stress–strain blank obtained from CA (containing history after FSW) coincides FE simulations. model, stress concentration factor, successfully predicts tensile behavior. both (METHOD 1 METHOD 2) coinciding other, except at initial stages forming.
