Traumatic Injury: Mechanical Response of Porcine Liver Tissue Under High Strain Rate Compression Testing

The injury metrics for dummies in car crash scenarios are typically force and acceleration; however, real injuries in humans are characterized by damage and fracture (rupture) processes of internal tissues and organs. An accurate prediction of the risk of these injuries using modeling and simulation requires knowledge of the mechanical properties of different human tissues/organs under various loading conditions. Especially in high-impact situations, quasi-static biomechanics may not be sufficient in characterizing the actual mechanical response of a tissue; therefore, high-strain rate testing becomes an area of interest [1].
