Multiresolution 2D geometric meshing for multiscale finite element analysis of bone micro-structures

Bones are composed of hierarchical bio-composite materials characterized by complex multiscale structural geometry and behaviour. Currently, there is great interest within the biomedical community in developing accurate non-invasive techniques for analysing bone micro-structure. We propose a new approach of multiscale finite element analysis of bone micro-structure which can provide physicians with a 'digital magnifying glass' providing a continuous bi-directional transition between macro-and micro-scales. In the macro-scale, the material appears to be smoother and more homogeneous. The zoomingin process reveals additional details and the heterogeneity of the material. In this paper we deal with the 2D geometric aspects, demonstrating the feasibility of the proposed method, using a multiscale domain-based geometric model.
