dc.description.abstractRad prikazuje analizu parametara mehanike loma višefazne Co-Cr legure, koja se koristi kao materijal za implant kod ugradnje veštačkog kuka. Konstrukcijski parametri koje bi trebalo uzeti u obzir tokom projektovanja implanta kod veštačkog kuka su zamor i lom. Ovaj rad se bavi elasto- plastičnom mehanikom loma komercijalnog hladno-vučenog (53%) MP35N (35% Co, 35% Ni, 20% Cr, i 10% Mo). U tom cilju sprovedeno je ispitivanje ponašanja na lom MP35N, pri čemu su urađena i statička ispitivanja (J-R kriva i JIc ispitivanje u skladu sa ASTM E1737) i ispitivanja udarom metodom po Šarpiju. Napravljen je pokušaj da se povežu vrednosti JIc sa prethodno dobijenim vrednostima KIc. Još jedan bitan zadatak bilo je ispitivanje odnosa između KVtotal i KIc, kao i između KVgrowth i JId. Rezultati ukazuju na dobro međusobno slaganje i na mogućnosti daljeg povećanja žilavosti.sr
dc.description.abstractThis paper presents an analysis from a fracture mechanical perspective of Co-Cr multiphase alloy materials that are used in total hip replacement implants. Design parameters to be considered for hip implants should be related to fatigue and fracture. This paper addresses the elastic-plastic fracture behaviour of commercially cold- drawn (53%) MP35N (35% Co, 35% Ni, 20% Cr, and 10% Mo). In this course, MP35N fracture behaviour has been investigated both under static loading conditions (J-R curve and JIc testing according to ASTM E1737) and under impact loading on Charpy instrumented pendulum. An attempt has been made to correlate JIc values with previously obtained KIc values. Another important task was to investigate the correlation between KVtotal and KIc and between KVgrowth and JId. These results indicate good mutual agreement and possible actions toward further increase of toughness.en
