A Strain Rate Dependent Constitutive Model for Liver Tissue: Experiments and Modeling

The mechanical characterization of liver tissue can be highly beneficial in the management of liver diseases and injuries (1). Liver is the most frequently injured abdominal organ due to injuries that are generally caused by motor vehicle accidents and falls from heights, both of which result in rapid decelerations (2). Moreover, in the US alone, more than 20,300 people die each year as a result of complications arising from chronic liver diseases and the associated fibrosis and cirrhosis.
