FARKLI OPTİMİZASYON YÖNTEMLERİNİN YLD2000 AKMA KRİTERİ KATSAYILARININ TAHMİNLERİNE ETKİLERİ
2019

The improved yield criteria are generally used in the finite element simulations of plastic deformation processes. Calculation accuracies of these criteria coefficients result successful simulation outcomes. In this study, the coefficients of the YLD2000 yield criterion are calculated by three most widely used optimization methods in literature, namely the least squares, nonlinear conditional optimization, and genetic algorithm methods. Two different aluminum alloys, AA7003-T6 and AA6063-T6 are
