Compressive behaviour of trabecular tissue: finite element modelling and comparison using digital volume correlation
Result description
In this paper the deformation behaviour of the complex structure of a trabecular bone is investigated using the finite element (FE) simulation of a compression test. To obtain a geometrically accurate FE model of the trabecular microstructure and suitable experimental data for model validation time?lapsemicro-CT scanning of the compression test was undertaken. The sample was placed in a loading device and subjected to incremental compressive loading (up to 6 % deformation with 1 % strain increments) andobserved using a fine?focus X-ray microradiographic imaging. Tomography of the sample was performed at each load step and the radiograms were reconstructed using the cone beam reconstruction technique to obtain spatial image data of the deformation process. Reconstructed image data of each load state enables the FE model to be valiated and the constitutive relations used for description of the deformation behaviour to be tested.
