Abstract
The paper is focused on the problem of liver characterization. The dynamic properties include very important information about behavior of tissue under impact loading. The work presents the methodology for testing the dynamic properties of the liver and parameter identification of Mooney-Rivlin hyperelastic material model. A measuring tip was hammered into the perfused liver with different deformation rates. The displacements of the liver surface were recorded using the ARAMIS system and the results were analyzed in GOM Correlate software. The experimental test was modeled and simulated using a finite element method (FEM). The obtained experimental data was used to validation a numerical model. Both experiments shows similar results for the same load and boundary conditions, what suggested that the numerical model was correct assumed.
