Application and comparison of failure theories

Tema ovog rada je primjena teorija čvrstoće, i njihova međusobna usporedba. U radu je detaljno analizirano i opisano šest teorija čvrstoća. Objašnjena je potreba za korištenjem teorija čvrstoća u inžinjerskoj praksi u svrhu predviđanja pojave loma krhkih i elastoplastičnih materijala pri višeosnom stanju naprezanja. Riješena su dva numerička primjera u kojima su prikazani rezultati proračuna po pojedinim teorijama čvrstoće, te njihove međusobne usporedbe.The subject of this thesis is the application of failure theories and their mutual comparison. Six failure theories are analyzed and described in detail. The necesity of applying failure theories in engineering practice to predict the occurrence of brittle and elastoplastic material fractures under multiaxial stress condition is explained. Two numerical examples were solved in which the results of the calculations according to the individual failure theories and their mutual comparison were presented
