Dynamic mechanical experiment on the arterial wall

摘要

In this paper, we review a method of mechanical experiment on the arterial wall and propose a dynamic mechanical experiment. We also do static experiment to compare with the dynamic one. We find that there is an offset between the dynamic curve and the static curve, that is to say, the ranges of radius in the dynamic and static experiments are different in the same range of pressure. The materials of the arterial wall have the property of self-adaptability in a mechanical environment. The increment elastic modulus of small deformation can not be obtained by differentiation directly from the stress-strain curve of large deformation.
