A study on effects of flaw shape idealization on the interaction of co-planar surface flaws subjected to tension load Universiteit Gent
Fatigue crack growth model incorporating surface waviness for Wire+Arc additively manufactured components Universiteit Gent
Wire+Arc additive manufacturing, due to its high deposition rate, is particularly suited for the construction and repair of large-scale components. For the very same reason, however, an important drawback of this process is the pronounced surface waviness. This waviness introduces multiple adjacent peaks and valleys at the component surface, acting as stress concentration sites which can undermine the fatigue performance. In the present work, ...

Influence of material heterogeneity on the strain capacity of pipelines Universiteit Gent
The strain capacity of pipes under combined loading is an important research topic within strain-based design. While strain capacity equations assume homogeneous pipe material properties, a realistic pipeline shows scatter in mechanical properties. Test and simulation programs have indicated that this "pipe heterogeneity" may reduce the tensile strain capacity under uniaxial loading by a factor up to two. To date, its effect in other scenarios ...
