Biomechanical Experimental Data Curation: An Example for Main Lumbar Spine Ligaments Characterization for a MBS Spine Model

摘要

This work overviews an extensive analysis in the context of mechanical characterization of human biomaterials, carried out over a broad set of published experimental data. Focused on main lumbar spine ligaments, several test procedures are exhaustively analyzed, in order to identify possible causes for divergences that have been found in some results. Moreover, guidelines are proposed for data filtering and selection. The main objective of the task was to retrieve trustworthy inputs to a hybrid Finite Element Analysis/Multibody System dynamic simulation model of the human intervertebral disc, which can be used on the prediction of nucleus prosthetics working performance.
