Fracture of Bone

Piekarski, K.·1970·Journal of Applied Physics

Abstract

Fracture of bone is investigated by measuring the energy required to propagate a crack and by observing, microscopically, the mechanism of fracture. At low strain rates bone displays very high resistance to crack propagation comparable even to some metallic materials. The type of fracture is similar to fiber-reinforced composite materials.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The velocity of trauma has an effect on how the fracture line propagates in bone.

    “This is in line with Piekarski’s [32] hypothesis that the velocity of trauma has an effect on how the fracture line propagates in bone.”
  • Our results differ from conclusions of other studies using animal bones, which suggested a preference for cracks to follow the path of least resistance, the cement line, at low loading rates.

    “Our results differ, however, from conclusions of other studies using animal bones, which suggested a preference for cracks to follow the path of least resistance, the cement line, at low loading rates [32,35].”
  • At higher strain rates, MCKs propagate through the microstructure without preference.

    “This supports literature stating that at higher strain rates MCKs propagate through the microstructure without preference [32].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
