Longitudinal fatigue crack propagation in compact bone
Membrane Transport Proteins
Molecular Dynamics Simulation
Fatigue tests of bovine compact bone specimens resulted in a strong correlation between the longitudinal fatigue crack propagation rate and the applied stress intensity at the tip of the crack. This correlation takes the form of a power law such as that found for other materials. Longitudinal fatigue crack propagation occurred by initiation and growth of subcritical cracks ahead of the main crack. Fatigue crack length was increased when the main crack joined with these smaller flaws.
