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…

Engineering components within a fusion reactor are subjected to extreme environments including high heat flux, strong magnetic fields, and neutron irradiation. Simulations are required to predict the in-service lifetimes of fusion components and ensuring credibility of these simulations requires validation over testable domains. Divertors are re…

Constitutive behaviour of fusion-relevant steels in the post-necking regime is necessary for detailed design of future fusion device components. A Finite Element Model Updating (FEMU) procedure using Digital Image Correlation (DIC), a simulated DIC filter and novel constitutive law was developed. The effects of the DIC process and experimental nois…
