| 摘 要： | 断裂力学是研究含裂纹构件裂纹的平衡、扩展和失稳规律，以保证构件安全工作的一门科学。断裂力学在航空、机械、化工、造船、交通和军工等领域都有广泛的应用前景，是一门具有高度实用价值的学科。20世纪60年代，国外开始应用断裂力学观点研究骨折的原理，认为断裂力学对研究骨的破坏是有意义的，断裂力学试验方法同样适用于骨的断裂研究，基于断裂力学研究骨骼的疲劳裂纹扩展逐渐成为研究的热点之一，因此有必要就断裂力学在应力性骨折中的研究进展进行综述。

| Abstract: | Fracture mechanics is a science to study the law of crack balance, propagation and instability in a cracked member. Fracture mechanics has a wide application prospect in aviation, machinery, chemical industry, shipbuilding, transportation and military industry and it is a subject with high practical value. Fracture mechanics has been used to study fracture since the 1960s abroad. Most scholars believe that is meaningful to study the destruction of the bone by fracture mechanics, fracture mechanics test method is also suitable for bone fracture. Bone fatigue crack propagation based on fracture mechanics research gradually become one of the hotspots of research. This article reviews the research development of fracture mechanics in the stress fractures. |
