This paper presents an experimental and numerical study of the effect of specimen thickness on the effective notch toughness Kmatρ for cleavage fracture measured using Single Edge Notch Bend (SENB) specimens containing a Unotch instead of a fatigue pre-crack. These specimens are typically used to measure a material’s effective notch toughness Km…

The Master Curve approach allows the full characterisation of the ductile to brittle transition region (DBTR) of ferritic steels to be performed with a reduced number of tests. In this paper, the approach has been combined with the application of the small punch (SP) tests. Modified SP specimens have been successfully employed to estimate the fract…

The detachment of a beryllium tile from the ITER Normal Heat Flux (NHF) First Wall (FW) panels would result in an unacceptable degradation of panel performance. Such detachment has previously been observed under High Heat flux (HHF) testing of NHF FW prototypes, with initiation of de-bonding at tile edges and subsequent delamination occurring betwe…
