dc.description.abstractPredložen je novi pristup projektovanju krive otpornosti prema prslinama i ispitana mogućnost njegove primene. Pristup se zasniva na opisu JR krive polinomom sa dva koeficijenta. Za određivanje koeficijenta su potrebna dva para vrednosti J integrala i širenja prsline Δa. Jedan od njih je određen eksperimentalno. Usvojeno je da drugi par pripada liniji zatupljivanja, ali su takođe potrebni i dodatni kriterijumi. Razmotrena je mogućnost kako da se uspostave ovakvi kriterijumi za drugi par vrednosti J integrala i širenja prsline Δa. .sr
dc.description.abstractNew approach for crack resistance curve design is proposed and the possibility of its application investigated. The approach is based on JR description by polynomial function with two coefficients. For determining coefficients two pairs of values of J integral and crack extension Δa are necessary. One of them is determined experimentally. It is accepted that the second pair of values belongs to the blunting line, but additional criteria are also required. The possibility to establish these criteria for the second pair of values of J integral and crack extension Δa is considered. .en
