Tungsten is the front-runner candidate for building the plasma-facing armour components for
future fusion reactors. However, in-service irradiation by fusion-neutrons and helium will …

Tungsten is used for vital applications in nuclear industry, particularly in experimental fusion
reactors like ITER. Experimental evaluation of the irradiation-induced hardening is usually …

Tungsten is considered as the plasma-facing material in the nuclear fusion device, which
has to withstand coupled irradiation, mechanical and thermal conditions. To guarantee the …

Predicting the dramatic changes in mechanical and physical properties caused by
irradiation damage is key for the design of future nuclear fission and fusion reactors. Self-ion …

Irradiation damage is known to alter a material's microstructure due to the accumulation of
high densities of defect clusters. Such irradiated microstructures change the mechanical …

In this work, a crystal plasticity finite element model is developed to simulate the spherical
nano-indentation of ion-irradiated metallic materials. Two critical features are addressed by …

The plasticity of tungsten in low or medium temperature regimes is dominated by the screw
dislocation mobility, which is well known to exhibit a strong non-Schmid effect and loading …

Coupling of nano-indentation and crystal plasticity finite element (CPFE) simulations is
widely used to quantitatively probe the small-scale mechanical behaviour of materials …

Abstract Crystal Plasticity Finite Element (CPFE), which merges crystal plasticity principles
with finite element analysis, can simulate the anisotropic grain-level mechanical behaviour …

The formation of prismatic dislocation loops during nanoindentation of bcc iron is simulated
with discrete dislocation plasticity. Interestingly, it is not the loading phase, but the unloading …
