Personnalisation morpho-mécanique de la voûte crânienne humaine à différentes vitesses de sollicitations

Abstract : Today, the digital models are usually used in the world of research, but also in industry, health, finance, etc.… The quality of the results will always be connected to the accuracy with which the engineer is able of formalizing the physical phenomena. More specifically in the biomechanical modelling, working with a high number of parameters, making very complicated the standardization of the models. This thesis has an approach of improvement in the quality of the digital models of the human skull through several studies having for aim the analysis of the morphological parameters of the skull and their use for the personalization of a morpho-mechanical model.The method of scan by micro-tomography was used to scan more than 360 samples taken from 10 skulls, and then mechanical tests of compression in quasi-statics and dynamics were led on a part of these samples. The results we obtained allowed us to develop a card of evolution of a number of morphological parameters of the skull based on a polynomial model. A statistical comparative study allowed to highlight the existing links between the morphology and the mechanical behaviour of these samples. Finally, the connection of these two studies allowed to propose a customizable morpho-mechanical model, and to validate it for various finite elements simulations on bones samples and on complete human skull.
