Biomechanical behavior study of dog‘s small intestines

The biomechanical behavior of dog's duodenum and jejunum were studied and a formulation of the stress-strain relation is presented in this paper,The results obtained indicated that the exponential coefficient α and the incremental duodenum of the elastic modulus are both larger than those of the jejunum.It means that the duodenum is more deformabel than the jejunum.The experimental results of this work provide basal data for kinematics study of a robotic endoscope.
