## Abstract The purpose of this investigation was to apply the techniques of fracture mechanics to a study of fatigue crack propagation in compact bone. Small cracks parallel to the long axis of the bone were initiated in standardized specimens of bovine bone. Crack growth was achieved by cyclicall
A theoretical method was developed for calculating the stress intensity factor (K) for semielliptical surface cracks in shafts subjected to a constant moment load. A number of tests using 2and 3-dimensional photoelasticity showed good agreement with the theoretical model. The calculated K was then u
In this paper the crack-growth resistance of wood is discussed on the basis of an energy consideration, The 'Nc-constant load-displacement curve' method has been used to obtain the crack-growth resistance curves for two different orientations of mode I fracture. These fracture resistance curves give
