中文摘要	The fracture is an important failure behavior of cancellous bone. Three-point-bending experiment was used to study fracture behavior of cancellous bone. Three group specimens were taken from two human femoral head and there was a non-angled crack and an angled crack in every group respectively. By using Digital Speckle Correlation Method (DSCM), the displacements and strain field were obtained at the crack-tip and the full specimen. The initial crack path was always at the maximal strain location and could be predicted by the DSCM. In the macro-scope, the crack propagation paths towards the load tip, and are independent of the initial crack angle.
