The Research Advances in the Flexible Tubular Organs Material

Article Preview

Abstract:

The domestic and foreign research situation of the biomechanical characteristics and rheological characteristics of the biological flexible tubular organs is introduced in this paper. The research includes the biomechanical characteristics of the cardiovascular system ,the trachea,the alimentary tract and the rheological characteristics of the blood, the mucus. The biomechanical characteristics of the biological flexible tubular organs divides into two parts: the stress-strain rule is researched through the one-dimensional or two-dimensional tensile experiments of the biological flexible tubular organs;the wall residual stress strain is researched for the biological flexible tubular organs in no load conditions. The stress-strain rule has been acquired through the one-dimensional or two-dimensional tensile experiments of the cardiovascular system, the trachea, the alimentary tract. The walls of the cardiovascular system ,the trachea,the alimentary tract have residual stress strain through measuring the opening angles.
