Résumé / Abstract
A theoretical modal analysis of a finite element model of the human head in its sagittal plane is proposed. The result applications to the crash biomechanics field are presented. Considering the response of a structure to a blow as a superposition of excited vibration modes, we show how occipital impacts lead to frontal injuries. This result is then illustrated in temporal field by calculating the brain motions and intracerebral stresses under impact conditions.
