Strain field measurements in polycrystalline tantalum
Résumé
The unterstanding and the local quantification of surface strain distribution is a key element of crack initiation analysis. Experiments following up the local strain distribution have been carried out, based on the construction of several hundred micrometers wide strain maps ; and using gratings of regularly spaced micrometric markers deposited by lithography. The strain maps are computed using a specific routine, allowing to quantify the local strain distribution at the grain scale for different interrupted tensile loads.
