Opredelitev elasto-plastičnega reološkega modela [alfa]-titanovih zlitin z inverzno numerično metodo : diplomska naloga univerzitetnega študijaJurendić, SebastijanZa potrebe numeričcnih simulacij preoblikovanja pločevine iz [alfa]-titanovih zlitin je opredeljen primeren materialni model, ki je sposoben zajeti bistvene lastnosti anizotropnega elasto-plastičnega ... odziva materiala. Obravnavan je modificiran Barlatov 1989 konstitutivni model, za katerega je določen postopek identifikacije parametrov materialnega modela ter za to potrebni mehanski preizkusi. Po inverzni numerični metodi, izvedeni na rezultatih nateznih preizkusov, so določene utrjevalne krivulje materiala v vzdolžni, diagonalni in prečni smeri. Vrednost parametra m materialnega modela je določena z inverzno numerično obravnavo erichsenovega preizkusa. Potrditev odziva materialnega modela je izvedena na nateznih preizkusih v različnih smereh glede na smer valjanja pločevine. Tako definiran materialni model je pokazal dobro ujemanje med izmerjenim in simuliranim odzivom materiala pri visokih plastičnih raztezkih in z zadostno natančnostjo zajame spreminjanje materialnih lastnosti glede na smer obremenjevanja.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [S.
