Abstract:
For the first pt.see ibid vol.11 no.4,p.241 (1989).The anterior interven-tricular branch aad the circumflex branch of the left coronary artery,and the right coronary were excised from 7 autopsy adult subjects without heart diseases.A biaxial loading test for the vascular specimens was completed,which was simultaneously finished in the internal thoracic artery(ITA) and the great saphenous vein (GSV) of the same subjects in order to compare with the coronary arteries.Stress-strain relationships of the vessels were expressed by the exponential strain energy function.The meaning of the two-dimensional material constants for the vessels are discussed.
