Abstract
In this review, we compare the reported values of Young's modulus (YM) obtained from indentation and tensile deformations of soft biological tissues. When the method of deformation is ignored, YM values for any given tissue typically span several orders of magnitude. If the method of deformation is considered, then a consistent and less ambiguous result emerges. On average, YM values for soft tissues are consistently lower when obtained by indentation deformations. We discuss the implications and potential impact of this finding.
摘要
在这篇综述中，我们比较了从软生物组织的压痕和拉伸变形中获得的杨氏模量 (YM) 的报告值。当忽略变形方法时，给定组织的 YM 值通常跨越几个数量级。如果考虑变形方法，则会出现一致且不模糊的结果。平均而言，通过压痕变形获得的软组织的 YM 值始终较低。我们讨论了这一发现的意义和潜在影响。
