Résumé / Abstract

Thoracic and abdominal organs are usually simulated in finite elements models (FEM) of the human body using viscoelastic or hyperelastic behaviour laws. Experimental investigations of organs mechanical behaviour under compressive loadings follow two ways: the use of tissu samples to give a local information that must be analyzed considering border effects or the whole structure behaviour evaluation. This last method, at the organ level, must be coupled to an inverse analysis to improve identification process. This work aims to build a methodology to implement the liver behaviour in a FEM that is robust enough to describe the biological, intrinsic and experimental variability. It is based on an ongoing experimental characterisation. liver; hyperelasticity; FE simulation; inverse analysis
