It is well known that the KIC test for determining static strength is not only very complicated compared with the tensile test but also very sensitive to specimen dimensions. For this reason the JIC test, which is not easy to perform, is often used thus it is desirable to establish a simple method for evaluating fracture toughness. In this study, we investigated the fracture toughness test by the unloading compliance method, and proved a method for estimating of fracture toughness by utilizing the tensile properties of metallic materials. In both methods, we used six kinds of steel, one titanium alloy and three aluminium alloys turned in the optional rolling direction (L-T, T-L). The following relation was observed between plane strain fracture toughness KIC and the uniaxial tensile properties obtained from JIS14A tensile specimens in rolled steels and non-ferrous metals. KIC=0.178[numerical formula]-4.0 (E : Young's modulus. σr : True fracture stress, εf : Fracture strain). It is possible to evaluate KIC within an estimated error of ±7%.
