梭图2.软骨在持续时间增加的负荷下的变形行为。当圣维南体内的载荷水平超过特征值时，模型允许永久变形。该模型将显示预期的永久变形，该变形可通过过度载荷和载荷持续时间的组合在组织中诱导。我们现在可以考虑这个模型所建议的一些临床研究。最基本的兴趣是骨组织的能量储存能力，特别是整个骨骼的能量储存能力。既然我们现在要讨论的是包括破坏在内的骨的性质，就有必要研究一些破坏准则。由于骨是非均匀和各向异性的，因此很难获得严格的三维标准，在此不作尝试。将使用简单基于一维情况的简化准则。麦克尔哈尼和拜尔斯
From C. Hirsch FIGURE 2. Deformation behavior of cartilage under increasing time duration of loading. model allow permanent deformation when the load level in the St. Venant body exceed a characteristic value. This model will display the desired permanent deformation which can be induced in tissue by a combination of excessive load and loading duration. We can now consider some of the clinical investigations which this model suggests. Of fundamental interest is the energy-storage capacity of bony tissue and in particular, the energy-storage capacity of whole bones. Since we would now like to deal with the properties of bone up to and including failure, it will be necessary to investigate some failure criteria. Since bone is nonhomogenous and anisotropic, a rigorous three dimensional criteria would be most difficult to obtain, and will not be attempted here. A simplified criteria, based simply on the one dimensional case will be used. McElhaney and Byars
