Abstract

Highlights: Progress with in situ stress rigs for automated 4D synchrotron experiments. A new Data management strategy for 4D experiments. A tomography 4D experiment with a polymer material to investigate deformation mechanisms. A tomography 4D experiment using a metallic alloy to study incipient plasticity. Abstract: This papers presents recent progress with materials investigations via in situ mechanical testing at the synchrotron, so called 4D experiments. More automated and more integrated stress rigs now allow to produce new kind of data sets to study deformation and fracture of structural materials. Two recent examples are presented, one with a polymer material and another one with a polycrystalline metallic alloy. Challenges with data organisation and storage and automatic analysis are discussed in the view of the upgrade of the main synchrotron sources which will greatly increase the number and size of the future data sets.
