提出了由指数形式的应变能函数推导出的动脉壁三维应力-应变关系。根据兔动脉在生理范围内受膨胀和纵向拉伸的实验数据，确定了材料常数。目的是：1)表明这样的程序是可行的和实用的，2)引起人们对血管壁上应力和应变的巨大变化的关注，假设组织是不可压缩的，当所有外部负载都被移除时，应力和应变是无压力的。
A three-dimensional stress-strain relationship derived from a strain energy function of the exponential form is proposed for the arterial wall. The material constants are identified from experimental data on rabbit arteries subjected to inflation and longitudinal stretch in the physiological range. The objectives are: 1) to show that such a procedure is feasible and practical, and 2) to call attention to the very large variations in stresses and strains across the vessel wall under the assumptions that the tissue is incompressible and stress-free when all external load is removed.
