This study presents a total of 38 uniaxial unconfined compression tests performed on human liver and spleen parenchyma specimens within 48 hours of death. The data show that the response of human liver and spleen parenchyma is both non-linear and rate dependent. In addition, the failure stress and strain of liver parenchyma was significantly greater than that of the spleen parenchyma at each loading rate. Overall, this study provides novel biomechanical data that can aid in the development of rate dependent material models and tissue level tolerance values, which are critical to the validation of FEMs used to assess injury risk in motor vehicle collisions.
