dc.description.abstractThe improved yield criteria are generally used in the finite element simulations of plastic deformationprocesses. Calculation accuracies of these criteria coefficients result successful simulation outcomes. In thisstudy, the coefficients of the YLD2000 yield criterion are calculated by three most widely used optimizationmethods in literature, namely the least squares, nonlinear conditional optimization, and genetic algorithmmethods. Two different aluminum alloys, AA7003-T6 and AA6063-T6 are selected to verify the predictionresults. Results reveal that the nonlinear conditional optimization and genetic algorithm methods are verydependent on the initial values. Therefore, different result is determined for each different case. For this reason,it has been concluded that the least squares method should be preferred to calculate the coefficients of the yieldcriterion by using optimizing method.
