Abstract: Researches focus on the aorta abdomen veins of the normal Chinese fresh dead bodies. Experiments are carried out on the stress relaxation and creep, thus obtaining the stress relaxation and creep data and curves of the aorta abdomen under the situation of constant stress and strain. Through regression analysis the authors obtain the reduced stress relaxation and creep functions. Finally, the results of the experiments* are analyzed and discussed.

Key words: aorta abdomen, viscoelasticity, reduced stress relaxation function, reduced creep function
