Notched small punch test (SPT) specimens with different types of notches have been adopted by many researchers to understand the fracture parameters of materials. However the specimen geometries have not been standardized and the effects of notch type on mechanical properties, failure mechanisms, and stress state of the tested materials need to be …

Creep-fatigue damage has been recognised as a critical failure mode for high-temperature structures. In fusion power reactors, plasma-facing components endure complex loading conditions, resulting in high thermomechanical stresses. These components, often made from 316L material, joined to ferritic-martensitic steels, face significant challenges du…

Crystal plasticity finite element (CPFE) modelling is an effective tool from which detailed information on the meso-scale behaviour of crystalline metallic systems can be extracted and used, not only to enhance the understanding of material behaviour under different loading conditions, but also to improve the structural integrity assessment of e…
