| Abstract: | By comparing the fracture curves of smooth thin-wall tubes with those of notched thin-wall tubes for some materials, we find out that the mode- I critical intensity factor Kic are the same for the two kinds of tests thus verifying the correctness of the testing method for determining the fracture toughness K_(ic) of ductile metals by using smooth thin-wall tube specimens. |
