三点弯曲法常用于组织材料性能的力学测定。当试样失效时，试样通常会发生很大的变形。本研究的目的是提出梁和板理论作为确定从弯曲到膜应力状态过渡期间拉伸和压缩弹性模量的分析工具。软骨是一种高度灵活的结缔组织，具有不同的拉伸和压缩模量。对猪耳（耳）和肋（肋）软骨进行三点弯曲试验。对跨长变化和泊松比假设的影响进行了统计分析。耳部和肋部的拉伸弹性模量分别为3.886 MPa和6.131 MPa。这里描述的功能评估可以作为组织重建和组织工程的设计输入方法，同时考虑到硬组织和软组织的应用。
Three-point bending is often used during the mechanical determination of tissue material properties. When taken to failure, the test samples often experience high deformations. The objective of this study was to present beam and plate theories as analytical tools for determining tensile and compressive elastic moduli during the transition from flexure to membrane stress states. Samples of cartilage, a highly flexible connective tissue having differing tensile and compressive moduli, were tested. Three-point bending tests were conducted on auricular (ear) and costal (rib) cartilage harvested from pigs. The influence of span length variation and Poisson’s ratio assumptions were statistically assessed. Tensile elastic moduli of the ear (3.886 MPa) and rib (6.131 MPa) were derived from high-deformation bending tests. The functional assessment described here can be applied as a design input approach for tissue reconstruction and tissue engineering, considering both hard and soft tissue applications.
