| Abstract |
Shear properties of bone have been inferred from torsion tests. However, torsion often causes spiral fracture planes that correspond to tensile rather than shear failure. We measured the shear properties of human cortical bone in both longitudinal and transverse directions using pure shear tests. Shearing applied transverse to the bone long axis caused fracture along a 45 degrees plane that coincided with maximum tension. This fracture pattern is similar to spiral fractures caused by torsion. Shear strength along the bone axis was 51.6 MPa or about 35% less than that determined using torsion tests. Fatigue tests of human cortical bone in pure shear were conducted. The results agreed well with previous measurements of cortical bone fatigue life in tension and compression, when normalized to strength. Using tibial shear strain magnitudes measured previously for human volunteers, we estimated the fatigue life of cortical bone for different activities, and speculate that shear fatigue failure is a probable cause of tibial stress fractures resulting from impact loading. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 11 August 2018.
All research outputs
#8,514,813
of 25,385,864 outputs
Outputs from Calcified Tissue International
#593
of 1,885 outputs
Outputs of similar age
#15,581
of 46,279 outputs
Outputs of similar age from Calcified Tissue International
#5
of 13 outputs
Altmetric has tracked 25,385,864 research outputs across all sources so far. This one is in the 43rd percentile – i.e., 43% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,885 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.0. This one is in the 35th percentile – i.e., 35% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 46,279 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 10th percentile – i.e., 10% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 13 others from the same source and published within six weeks on either side of this one. This one is in the 7th percentile – i.e., 7% of its contemporaries scored the same or lower than it.
