Dr Olga Barrera’s lab: Oxford image-based multi-physics modelling of multi-phase materials.
Keywords: Artefact free imaging, high resolution micro-CT scans, experimental in situ mechanical/poromechanics testing, Image-base pore scale modelling, fractional poroelasticity
Dr Barrera’s research focuses on a combination of computational methods, digital microstructure and innovative experimental techniques to understand the behavior of a range of materials with a particular focus on soft tissues having load bearing function.
Summary of activities:
Current funded projects:
- Characterisation of bio-inspired dampers Relevant for impact energy Absorption in Sporting Health applications (CRASH).
