Michael Hofmann

Diffraction methods are powerful tools for non-destructive analysis of applied or residual stresses. The high penetrating power of neutrons when compared to laboratory x-ray sources, i.e. several cm instead of a few tens of μm, opens up the possibility to analyze residual stresses in the interior of technical components rather than just at the surface. This makes neutrons an ideal tool for...

Diogo Goncalvez (CEA)

23/11/2022, 10:00

Manufacturing processes results in residual stresses that can be high enough to plastically deform the material. The superposition of residual stresses to those resulting from external loadings can not only contribute to premature failure of structural components, but also affect the driving force for crack initiation and propagation.
In the last year, crack problems have been reported in the...
