According to the latest research the nonlinear elastic model with hysteresis is the
most realistic to model the blood
vessel. Relationship between the transmural pressure and external diameter of the
blood vessel, modelled by a silicon elastomer tube is studied under stress. This paper
focuses on the measurement method using digital image processing. Edge detection algorithms
are developed using Matlab software
environment to determine the diameter of the tube under specific inner pressure. Results
reproduce the static and dynamic behaviour of the silicon elastomer material.
