Compact bone fatigue damage--I. Residual strength and stiffness.

Abstract Residual strength and stiffness of compact bovine bone specimens during fatigue were investigated and the fracture surfaces were examined by scanning electron microscopy. Residual strength tests consisted of rotating bending fatigue followed by tensile tests to failure. Specimens loaded to 50% of their fatigue lives had approximately a 13% loss of tensile strength ( p
