摘要
本研究考虑密质骨的粘弹性性能,在连续损伤力学的框架范围内研究了密质骨的本构模型,分别就细观结构强度服从均匀分布和非均匀分布两种情况进行了讨论。实验研究表明,该损伤模型是可取的。
A damage model of compact bone with Haversian structure is proposed in this paper. The model is developed within the general framework of the CDM (continuum damage mechanics) through consideration of the irreversible changes of the mesostructure and the viscoelastic properties of bone. The correctness of this model is verified through the tensile tests of human wet compact bone specimens and the observations of the fracture surfaces of the specimens by scanning electron microscope.
