Numerical and experimental analysis of the tool geometry on states of stresses and strains during shear slitting of aluminum alloys

Abstract: W pracy zbadano wpływ geometrii narzędzia tnącego na przebieg procesu cięcia i jakość uzyskanej powierzchni przecięcia dla stopu aluminium AA6111-T4 kształtowanego na nożycach krążkowych. Przedstawiono sposób modelowania procesu cięcia na nożycach krążkowych metodą elementów skończonych w Solwerze LS-DYNA. Opracowano aplikacje komputerowe umożliwiające m.in. analizę stanów naprężeń i odkształceń występujących podczas i po procesie cięcia, analizę nacisków kontaktowych, ocenę jakości powierzchni przecięcia pod … Show more
