Abstract
Hydrogen can substantially increase the material degradation under cyclic loading. During short fatigue crack growth, which is often the dominating stage during crack propagation, the crack growth rate is highly influenced by microstructural characteristics such as grain boundaries, the formation of slip bands and the local concentration of hydrogen at the crack tip. To address the problem of prediciting the short crack growth behavior, a multi‐physics approach is presented accounting for these interacting influences.Keywords
