Nettet9. des. 2002 · Diese Vorgehensweise ist mit entsprechenden Unsicherheiten behaftet. Am Beispiel einer Al-Legierung vom Typ AlMgMn (Blechdicke 0,75 mm) im weichgeglühten Zustand (wg) wird gezeigt, dass bekannte Verfestigungsmodelle (Swift, Voce, Hockett-Sherby) zu signifikant abweichenden Extrapolationen der Fließwiderstandskurve führen.

NettetIn current forming simulations, Ghosh or Hockett-Sherby extrapolation functions are used to model strain hardening effects of sheet metals. When it comes to stochastic simulations, the respective parameters have to be recalculated according to the scattering of the mechanical material properties like yield or tensile strength. As present stochastic …
