Abstract Scope |
Mechanical testing inside industrial microCT scanners provides exciting insight into microstructure and damage accumulation in composites, metals and additively manufactured metamaterials. Digital Volume Correlation can reveal small-scale mechanism that collectively produce a material’s continuum level response. Support posts in typical load frames obstruct X-rays during sample rotation. A test system that rotates the load train within the frame is presented. The rotating load train maximizes spatial resolution by enabling source placement close to the sample. The frame constrains out-of-plane motion and wobble though precision machining and design symmetry. A sub-micron alignment correction algorithm is also presented. |
