Measurement of the Mechanical Properties of the Pig Liver and Spleen

Abstract

Mechanical properties of pig liver and spleen were measured in tension and compression test. Test pieces of the liver parenchyma, the liver capsule, and the spleen parenchyma were obtained from edible pigs in order to examine the tensile and compressive strength, stress-strain curve and Poisson's ratio. The spleen tissues are larger than the liver tissues in terms of the strain at the same stress and in maximum strain, but in terms of maximum stress, the liver tissues are larger than the spleen. The difference of the strain at the same stress between parenchyma and capsule are larger in the spleen than in the liver.
