根据电子显微镜的研究,骨中微裂纹形成和扩展的初始阶段被描述为银纹状现象。通过比较不同实验条件下的微观和纳米变形和断裂过程,得出银纹化是骨损伤和断裂过程中最基本的微观力学过程的结论。尽管银纹与聚合物材料中的银纹有着惊人的相似之处,但骨中银纹的形成和生长受到骨基质的主要组成部分--矿化的胶原纤维的形态以及骨结构的显著各向异性的强烈影响。
Based on electron microscopic investigations, initial stages of microcrack formation and growth in bone are described as craze‐like phenomena. The comparison of micro‐ and nanoscopic processes of deformation and fracture induced under different experimental conditions give rise to the conclusion that crazing is a fundamental micromechanical process during bone damage and fracture. Although there are striking similarities to crazes in polymeric materials, craze formation and growth in bone is strongly influenced by the morphology of the main building blocks of the bone matrix, i.e., the mineralized collagen fibrils, as well as by the significant anisotropy of bone architecture.
