Conference paper

Summary

Stress distribution through the wall thickness of the artery was analyzed on the basis of the uniform strain hypothesis which assumes that the wall circumferential strain is constant over the wall cross-section under the physiological loading condition. In contrast with the results calculated using the conventional zero initial stress hypothesis which assumes that there is no stress when all external loads are removed, the uniform strain hypothesis yielded almost uniform distribution of wall stresses under the physiological condition and non-zero residual stresses even when all external forces were removed.
