| Streszczenie: | Hydrogen embrittlement is a major and longstanding challenge in materials science. Mesoscale mechanical models are currently being developed which are providing new insight into hydrogen-dislocation interactions and the subsequent detrimental effect on ductility and ultimate tensile strength. Here, a review of some recent approaches to incorporating hydrogen within crystal plasticity, discrete dislocation plasticity and cohesive zone models are reviewed. Modelling at this scale bridges the gap between atomistic models and continuum engineering models which will be essential to fully understand hydrogen embrittlement. |
