Qualification of AM parts: the application of extreme value statistics for volumetric defect analysis
14th European Conference on Spacecraft Structures, Materials and …, 2016•researchgate.net
… Prediction of the fatigue strength of homogeneous material volumes for the qualification
of AM parts. How? Analysis of witness specimens by computed tomography (CT) and
application of extreme value statistics. … • Large defects are caused by lack of fusion,
elongated perpendicularly to the build direction; • Comparable exponential distributions of
large defects; • POT is simple and yields good extreme value estimates; • Defects at the
origin of failure are well described by the distribution of the maxima in the gage volume; • …
