Abstract
U ovom radu razmatra se određivanje parametara anizotropnih uvjeta tečenja Hill-48 i Karafillis-Boyce. Prikazan su standardni načini proračuna parametara ovih uvjeta na temelju tri vrijednosti naprezanja tečenja koje odgovaraju orijentacijama 0°, 45° i 90° i vrijednosti naprezanja tečenja za ujednačeno dvoosno stanje naprezanja. Standardnim proračunom za Hill-48 uvjet tečenja parametri se računaju na temelju jednostavnih analitičkih izraza. Za Karafillis-Boyce uvjet standardni način proračuna parametara koristi iterativni NewtonRaphsonov postupak. U radu se razmatra primjena genetskih algoritama u određivanju parametara Hill-48 i Karafillis-Boyce uvjeta tečenja na temelju većeg broja vrijednosti naprezanja tečenja. Standardni način proračuna i proračun genetskim algoritmom primijenjeni su za lim aluminijske legure AA2090-T3. Analiziran je utjecaj postavki genetskog algoritma na rješenja parametara. Analizirana su predviđanja orijentacijskih ovisnosti i kontura tečenja koja se dobiju funkcijama tečenja s parametrima određenim razmatranim pristupima.
Abstract (english)
In this paper, the determination of the parameters of Hill-48 and Karafillis-Boyce anisotropic yield criteria is considered. Standard ways of calculating the parameters of these criteria based on three yield stress values corresponding to orientations 0°, 45° and 90° and yield stress value for balanced biaxial stress state are presented. The standard calculation for the Hill-48 yield criteria parameters is based on simple analytical expressions. For the KarafillisBoyce yield criteria, the standard method of parameter calculation uses the iterative Newton-Raphson procedure. The paper considers the application of genetic algorithms in the determination of Hill-48 and Karafillis-Boyce yield criteria parameters based on a larger number of yield stress values. The standard calculation method and the genetic algorithm were applied to AA2090-T3 aluminum alloy sheet. The impact of genetic algorithm settings on parameter solutions was analyzed. Predictions of orientation dependences and yield contours obtained by yield functions with parameters determined by the considered approaches were analyzed.
