升主动脉黏弹性实验研究

Experimental Study on the Viscoelasticity of Aorta Ascendens

对正常国人急性头部外伤致死的新鲜尸体升主动脉进行应力松弛 ,蠕变实验研究 ,得出了升主动脉的应力松弛 ,蠕变数据和曲线。用回归分析的方法处理实验数据 ,得出了归一化应力松弛函数和归一化蠕变函数 。

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.
