Abstract

U radu je obrađena tema teorija čvrstoće kao kriterija loma ili plastičnosti za homogene i izotropne materijale. U prvom dijelu je opisana teorijska pozadina potrebe za korištenjem teorija čvrstoća. Drugi dio sadrži objašnjenje teorija čvrstoće koje se koriste u inženjerskoj praksi kako bi se predvidio slom materijala pri višeosnom stanju naprezanja. U trećem dijelu je prikazana usporedba teorija čvrstoće s osvrtom na prikladnost njihove upotrebe kod različitih vrsta materijala. Rad sadrži i riješene zadatke te usporedbu rezultata proračuna po pojedinim teorijama čvrstoće.

Abstract (english)

This thesis elaborates theories of failure as criteria of fracture or yielding for homogeneous and isotropic materials. The first part explains the theoretical background of reasons for using theories of failure. The second part contains explanations of failure theories which are used in engineering practice in order to predict the material failure in multiaxial stress state. Third part contains the comparison of failure theories with emphasis on their usage for different types of materials. The thesis also contains solved problem examples and comparison of calculation results according to different failure theories.
