[Experimental study on the viscoelasticity of aorta ascendens]

We carried out the stress relaxation and creep experiments on the aorta ascendens of five fresh dead bodies of normal chinese men who had died from impetuous trauma on the head. The stress relaxation and creep data and curves of the aorta ascendens were obtained. Then regression analysis was performed to get the reduced stress relaxation and creep functions. Finally, we analyzed and discussed the results of the experiment.
