An experimental technique for studying dynamic fracture toughness under stress wave loading is described in this paper. With a Bar Impact Testing Machine, the three point bending specimen was fractured under impact loading, the loading rate K, being approximately lo6 N/mm3'2. s. An accurate measurem
The relationship between the three point bend (TPB) specimen size and the measured fracture toughness K,, value is analyzed by the theory of crack opening displacement (COD). According to the concept of plane strain fracture toughness K,,, a new formula for K,, is presented. For small-scale or large
By using the self-designed Rotating Circular Disk direct tensile impact apparatus, a novel test method has been developed for studying the fracture properties of materials under impact loading. A double edge notch specimen under a plane stress state is used in fracture test conditions; the material
