Vermoeiingsanalyse van proefstukken die vervaardigd zijn met laagsgewijze productietechnieken.

The worldwide use of Additieve manufacturing techniques such as selective laser sintering (SLS) and selective laser melting (SLM) is growing and components are used more and more in functional applications. However, the fatigue and failure properties of these materials are still largely unknown. Consequently, for safety-critical components, conventional production techniques are preferred. In the PhD-study of Brecht Van Hooreweder, a first step has been made to address this by analysing the fatigue failure mechanisms of SLS specimens in polyamide and SLM specimens in titanium. This work has been performed in close collaboration with Prof. Kruth, researchers from the Material Science Department, and scientists from the University of Cape Town in South-Africa. During the postdoctoral project, this first fatigue analysis will be continued and extended by using the fatigue test rig developed in the previous project. With this test rig, the multi-axial fatigue properties can be studied. This work will be done in close collaboration with researchers from the university of Sheffield.
