title: [Experimental research on mechanical behavior of human placenta].
abstract: OBJECTIVE
  Determination of mechanical properties of human placenta.
  
  
  METHODS
  Realisation of an experimental study using 80 human placentas and modelisation of this study using a finite element numerical model. Using the inverse analysis method, research of the parameters of placenta's behavior.
  
  
  RESULTS
  Hyper-Visco-Elastic law written by Ogden, optimized for placenta with parameters: mu(1)=0.0001881Mpa, mu(2)=-0.000240Mpa, mu(3)=mu(4)=0Mpa and alpha(1)=2, alpha(2)=-8, alpha(3)=alpha(4)=0 in static condition.
  
  
  CONCLUSIONS
  The parameters enable an approach of the mechanical behavior of the placenta. They could be used in numerical modelisation.
