title: [Study of the mechanical properties of liver by the method of compression deformation. Viscous-elastic properties].
abstract: Mechanical properties of rat liver samples under tension relaxation at stable values of deformation were studied. For describing tension relaxation a model was used which consisted of two viscose-elastic Maxwell elements connected in parallel with two relaxation times. It was found that the basic elements of the model -- E1, E2, eta 1 and eta 2 depended on the deformation value and can be described by means of exponential relationship. A conclusion is made on the strength of the data obtained about non-linearity of viscose-elastic properties of the liver. It is suggested to be concerned with both parenchyme properties and with the peculiarities of its microstructure.
