Quantitative Deformations- und Rißspitzenanalyse mittels Mikro-Moire-Technik im REM

A hybrid experimental and numerical approach for the determination of microdeformations and fracture quantities is presented on the example of aluminum CT-specimens. The micro moiré technique is used in a scanning electron microscope combined with 3d finite element analysis of the specimen. Fracture and crack tip quantities have been obtained.
