摘要	Although the testing method for fracture toughness K-IC has been implemented for decades, the strict specimen size requirements make it difficult to get the accurate K-IC for the high-toughness materials. In this study, different specimen sizes of high-strength steels were adopted in fracture toughness testing. Through the observations on the fracture surfaces of the K-IC specimen, it is shown that the fracture energy can be divided into 2 distinct parts: (1) the energy for flat fracture and (2) the energy for shear fracture. According to the energy criterion, the K-IC values can be acquired by small-size specimens through derivation. The results reveal that the estimated toughness value is consistent with the experimental data. The new method would be widely applied to predict the fracture toughness of metallic materials with small-size specimens.
