由Shoemaker（博士论文，1984）提出的一个本构关系来模拟膜状或二维软组织的力学行为。Schneider（博士论文，1982）和Lee等人的人体皮肤实验。j .杂志。本文讨论了本构模型在犬心包实验中的应用，以及本构模型在双轴应力-应变数据中的应用。文中给出了用曲线拟合得到的模型的一些实验数据和预测结果，以供比较。给出了材料参数的取值。结论是，本构模型能够很好地拟合单个试验的结果，其通用性（通过同一试样的试验参数的一致性来判断）虽然不完全，但与文献中提出的其他一些结果相比，确实是有利的。
A constitutive relation proposed by Shoemaker (Ph.D. dissertation, 1984) to model the mechanical behavior of membraneous or two-dimensional soft tissues is described. Experiments by Schneider (Ph.D. dissertation, 1982) on human skin and Lee et al. (Am. J. Physiol., 249, H222-H230, 1985) on canine pericardium, and the application of the constitutive model to biaxial stress-strain data from these experiments, are discussed. Some experimental data and predictions of the model obtained by curvefitting are presented for comparison. Values of material parameters are also presented. It is concluded that the constitutive model is well able to fit results of individual tests, and that its generality (judged by consistency of parameters from test to test of the same specimen), though not complete, does compare favorably with some other results presented in the literature.
