چکیده مقاله:
CuZn۴۰ brass alloy with ۳۸-۴۲% zinc content has different applications regarding its formability and machinability properties. In this study, friction stir welding (FSW) of CuZn۴۰ brass alloy was performed by selecting the specified welding parameters according to the design of experiment (DOE) table. Regarding to the response surface method (RSM) with central composite design (CCD), an optimization was done according to the results of the specimen tensile test and the final function related to it was extracted. In order to achieve a predictive finite element model, an attempt was first made to consider all simulation cases regarding the experimental test. Then, by calibrating the model, while placing the optimal parameters in it, the temperature results were compared in practical mode and simulation. Finally, the relationship between welding parameters and ultimate tensile strength was investigated.
