A multifunctional mechanical testing stage for micro x-ray computed tomography

An existing open and modular designed micro X-Ray Computed Tomography (μXRCT) system is extended by a test rig in order to combine mechanical hydro-mechanical experiments with μXRCT characterization. The aim of the cover complete resolution range underlying combination broad load capacity range. A characteristic feature developed setup that it consists mainly standard components. This makes shown potentially interesting for other researchers considering extending an apparatus situ testing. For frame, uniaxial 10 kN universal testing machine digital control was employed, which two aligned rotational stages. ±3.1 can be combined torque moments up ±15 N m both limited used such way different x-ray transparent cells (flow cells, oedometer triaxial etc.) integrated generate three-dimensional stress/strain states as required porous media research. Three applications demonstrate possible versatile use system. As part these examples, we show how corresponding are implemented. Finally, discuss presented approach’s technical advantages disadvantages suggest improvements.
