cze	Stanovení lomové houževnatosti ocelí použitím vrubovaných kruhových vzorků	Standardizované metody stanovení lomové houževnatosti jsou finančně i časové náročné. V prezentované práci je lomová houževnatost stanovena použitím krohových vzorků; tato nestandardní metoda představuje zjednodušený přístup k hodnocení, který byl ověřován.	lomová houževnatost, kruhové vrubované vzorky, vzorky s iniciovanou trhlinou
eng	Determination of Fracture Toughness of Steels Using Circumferentially Notched Round Bars	Determination of fracture toughness is possible using a compact tension specimen, a single edge notched bend or three-point loaded bend specimen, which are standardized by the American Society for Testing and Materials (ASTM) as well as other institutions. Researchers emphasize that these standardized methods are complex, the manufacturing process is difficult, they require special fixtures for loading during the experiment and the test procedures are time consuming. By means of fracture load values, fracture toughness using round bar speciments was determined by the proposed equations in this work. It can be stated that this approache for calculating fracture toughness is simple, fast and economical and worth validating.	fracture toughness, notched round bars, pre-cracked specimen
