The hyperelastic and viscoelastic properties of liver are important to determine its hemodynamic behaviour for a given portal blood inflow. Hyperpressurization of the organ is one of the major causes of malfunction and disease. In this work elastomer foams of different densities were selected to construct mock-ups capable of mimicking rat livers (investigated in another work presented to this Conference) in a number of characteristic tests. The results of these tests are shown and discussed.

Abstract
The hyperelastic and viscoelastic properties of liver are important to determine its hemodynamic behaviour for a given portal blood inflow. Hyperpressurization of the organ is one of the major causes of malfunction and disease. In this work elastomer foams of different densities were selected to construct mock-ups capable of mimicking rat livers (investigated in another work presented to this Conference) in a number of characteristic tests. The results of these tests are shown and discussed.
