Three separate two-dimensional plane strain finite element models of the head, each of which incorporated the skull, the cerebrospinal fluid and the brain, were constructed. Two of these models represented the coronal plane of the head as being elliptic whilst the third model was geometrically representative of an actual human head. This third model was taken in an off-centre mid-sagittal plane in an anterior–posterior direction and all three models were used to investigate the dynamic response of the human head when subject to direct translational impact events. The physiological consequences of modelling the human brain as being elastic were established. Compressive and tensile strains were predicted at the coup and contrecoup sites for a simulated frontal impact event by means of a simple elastic analysis. These distributions of most severe strain correspond directly to the occurrence of coup and contrecoup contusion such as are witnessed in clinical studies which arise under the action of translational acceleration.||Type of material:||Journal Article||Publisher:||Springer-Verlag||Journal:||Computational Mechanics||Volume:||26||Issue:||3||Start page:||229||End page:||235||Copyright (published version):||2000 Springer-Verlag||Keywords:||Contusion; Frontal; Impact; Brain; Trauma; Head; Injury; Translational (linear) acceleration||DOI:||10.1007/s004660000179||Language:||en||Status of Item:||Peer reviewed|
