Progress of Research on Injury Biomechanical Model and Tests of Human Liver in Impact

Abdominal blunt injury is common in vehicular accidents. Liver injury is one of the most severe traffic trauma. Currently, the research objective of human liver biomechanics is the development of high-biofidelity model describing human liver dynamic response and mechanism characteristics, the analysis of relationship between structures and mechanical factors in different loading conditions, to find ways reducing liver injuries in impact. The research summary has been conducted in development and application of liver finite element model, discussion of liver material characteristics and conclusion of liver external experiments.
