Fracture mechanics applications of absorbed specific fracture energy: Notch and unnotched specimens

Abstract The Absorbed Specific Fracture Energy (ASFE) ∗ is an energy criterion that may be applied to evaluate the embrittlement and fracture properties of low and medium strength structural materials. Some new results are presented to illustrate the application of ASFE, and relating them to the other fracture criteria such as J1c and K1c. A comparison of results is made for static and dynamic loading, and the influence of neutron irradiation.
