TL;DR: In this article, the elastic T-stress is calculated for a range of two and three-dimensional cracked geometries and some new results calculated at AEA Technology are presented.

TL;DR: In this paper, a series of Lookup Tables and functions are derived which enable parameters to be readily established based on a knowledge of the yield and work hardening behaviour of the material at the temperature of interest and the Beremin cleavage fracture model parameter m. These are provided for use where cracktip constraint is quantified either in terms of the elastic T-stress normalised by the yield stress or the elastic-plastic Q-stress.

TL;DR: Developments in constraint-based approaches to be applied to the practical assessment of defective components are described and how the methods have been included in the overall SINTAP procedures are indicated.

TL;DR: In this article, a number of constraint-based approaches have been applied to the practical assessment of defective components, including surface defects, secondary stresses, and simplified weight function methods for calculation of T-stress and relevant fracture toughness data.

TL;DR: In this paper, the effects of oxygen content on the microstructure and Charpy impact properties of HIP-d austenitic stainless steel, through combination of detailed metallographic examination and mechanical testing on HIP’d Type 316L steel containing different concentrations (100 to 190 ppm) of oxygen.
