eng	Determination of Fracture Toughness of Metallic Materials Using Round Bar Specimen	In this work, two different approaches for fracture toughness are investigated for S355 and Strenx700MC steels. In the first method, a circumferentially cracked round bar was loaded in tensile mode and pulled till failure. Using suitable equations, fracture toughness can be calculated. In the second method, a circumferentially notched bar specimen without fatigue pre-cracking was loaded in a tensile machine. By means of fracture load values, fracture toughness was determined by the proposed equations.	fracture toughness, notched round bars, pre-cracked specimen
