Digital Volume Correlation (DVC)
3D imaging can be used to analyse the geometry and morphometry of different types of (bio)materials. Using acquired images during time-lapse mechanical testing, it is possible to measure displacement and deformation fields with digital volume correlation (DVC).
This approach can visualise in 4D (space and load) the obtained results for better understanding the failure mechanism in the considered specimens. The obtained data can also be used to validate the outputs of computational models.
Examples of applications:
- About the inevitable compromise between spatial resolution and accuracy of strain measurement for bone tissue: a 3D zero-strain study
- Micro-CT based finite element models of cancellous bone predict accurately displacement once the boundary condition is well replicated: A validation study
- Validation of finite element models of the mouse tibia using digital volume correlation
