摘要：
A new method of characterizing the fracture arrest capabilities of structural steels is described. The method employs wedge-loaded ″duplex″ double-cantilever-beam (DCB) specimens and a fully dynamic analysis of crack propagation in the test piece. The analysis of the test data lends support to the view that kinetic energy contributes to the crack driving force, and that the static stress intensity at arrest is not a material property.
