- This study is part of a STFC-Diamond (MG22575) and industrial (Biotrics, ~£93k) funding and produced the first ground-breaking use of digital volume correlation (DVC) in bone tissue, based on simultaneous continuous compression and synchrotron X-ray computed tomography (SR-XCT). This allowed the evaluation of 3D full-field strain evolution and failure pattern following cyclic loading, indicating the reduced ability of bone to plastically deform after damage accumulation from cyclic loads. SR-XCT dynamic experiments will be the future for evaluating the time-dependent mechanical behaviour of biomaterials, paving the way to a new understanding of clinical conditions on the biomechanical response of biological tissues.
