概要
Abstract This paper considered i) thickness effect and ii) difference in test specimen structure, on the fracture toughness of a material in the transition temperature region. First, the thickness effect on the T33-stress, which is the out-of-plane elastic crack tip constrain t parameter, was studied. Then, an experimental expression on thickness effect on the fracture toughness by using T33-stress was proposed for carbon steel S55C, for 3PB (3 point bending). Finally, this experimental expression was shown to describe difference in CT specimens.
