Popis: | The slitting method has become well-established for determining residual stresses in engineering materials. This study develops and applies a version of that method using a small slot to find residual stresses vs. depth in layers near the surface of bovine femurs. Results are obtained for the central region (diaphysis) of hydrated femurs from both mature and young cows. The magnitude of residual stresses was found to be greatest in thin layers near the surface, typically 100–200 μm deep. Residual stresses in those layers were compressive in mature femurs at the circumferential location tested, but tensile in hydrated young femurs. |
