N2 - Micro-finite element (μFE) models are able to predictthe mechanical behaviour of bone at the tissue level.Their validation on the macro-scale has already beenachieved by comparing predicted apparent mechanicalproperties with experimental measurements. Recently,Digital Volume Correlation (DVC) enabled thevalidation of μFE models at the meso-scale in the elasticregime [1], but a validation of models including materialnonlinearities has not been conducted yet. The goal ofthis study was to validate the highly efficient μFE solverParOSol [2] at the meso-scale (~ 1mm) using DVCdisplacements measured in human trabecular bonespecimens tested up to failure. The study compares thepredicted displacement fields of different linear andmaterially nonlinear [2] μFE simulation methods.
