Early work showed that there was a fracture toughness peak (FTP) as the fracture toughness changed with crack length/specimen width (aj W). It could be thought of as a "safe crack" for the cracks whose length is smaller than that where the FTP is located. In the present paper, it is indicated that t

โฆ Synopsis
The application of Weibull statistics to predictions of specimen size eflects on Kr, in wood is discussed and found to be inappropriate. Plane stress conditions induce high energy absorbing microstructural deformation mechanisms and lead to crack front tunnelling under both static and fatigue loading.

In this investigation, five estimation methods have been adopted to estimate the dynamic fracture toughness of a nuclear pressure vessel steel A508 CL3 by using pre-cracked Charpy-size specimens on an instrumented impact test machine. Furthermore, the merits and the demerits of the five methods have
