Shear properties of bone have been inferred from torsion tests. [...] Key Method 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…Expand

Shear deformation and fracture of human cortical bone.
TLDR
It is concluded that shear-induced microcracking of human cortical bone follows a unique pattern that is governed by the lamellar structure of the osteons. Expand
Progressive post-yield behavior of human cortical bone in shear.
TLDR
The results of this study suggest that the intrinsic mechanism of plastic deformation of human cortical bone may be independent of loading modes. Expand
Comparative Study of Locational Variation in Shear and Transverse Elastic Modulus of Buffalo Cortical Bone
Abstract The heterogeneous nature of bone material is responsible for locational variation in its mechanical properties whereas its anisotropic nature makes these properties to be directional.… Expand
Differences in the mechanical behavior of cortical bone between compression and tension when subjected to progressive loading.
TLDR
It is found that bone dissipated greater energy through the mechanisms of permanent and viscoelastic deformation in compression than in tension, and that differences in damage morphology between the two loading modes may favor the plastic and visCoelastic energy dissipation in compression, but facilitate the surface energy release in tension. Expand
Strain patterns during tensile, compressive, and shear fatigue of human cortical bone and implications for bone biomechanics.
TLDR
The overall hypothesis of this investigation is that there is a common underlying factor in the damage-related behavior of bone, which may allow us to link together the various aspects of the damage relatedbehavior of bone. Expand
Understanding the etiology of the posteromedial tibial stress fracture.
TLDR
Based on predictions from ex vivo studies, stair and vertical jumping tibial shear strain in the test subject was high enough to potentially produce tibIAL stress fracture subsequent to repetitive cyclic loading without necessarily requiring an intermediate remodeling response to microdamage.

Non-linear shear behaviour of bovine cortical bone by coupling the Arcan test with digital image correlation
Abstract The non-linear shear behaviour of bovine cortical bone is measured by coupling the Arcan test with digital image correlation. The experimental study is carried out on specimens taken from… Expand
Tension and Compression Testing of Cortical Bone
Abstract Cortical bone is a biological tissue, which acts as the external shell for all bones in the human body. As a natural composite material with a hierarchical structure, cortical bone mainly… Expand
Fatigue strength of human cortical bone: age, physical, and material heterogeneity effects.
TLDR
The present results indicate that, perhaps, heterogeneity not only influences the initiation of microcracks, but also their eventual growth and coalescence into larger cracks, which are detrimental for the integrity of the material. Expand

TLDR
Fatigue behavior of bone was found to be uniquely related to the individual mechanical components of physiological loading and the latter determined the specific damage mechanisms associated with fatigue fracture. Expand

Data for load histories involving both tensile and compressive loading indicate lower time to failure than predicted by a simple summation of time-dependent and cycle-dependent damage. Expand

TLDR
The results suggest that the fatigue strength of cortical bone at 107 cycles may be closer to 7 than 40 MPa as indicated by previous bending fatigue tests and that fatigue is more strongly controlled by strain range than stress range. Expand
Cyclic mechanical property degradation during fatigue loading of cortical bone.

The findings suggest that secant modulus degradation and cyclic energy dissipation are greatly increased at loading levels above critical damage strain thresholds of 2500 and 4000 mu epsilon in tensile and compressive fatigue, respectively. Expand

TLDR
The changing shape of the third metacarpal bone during maturation may be consistent with the lower strains recorded during high speed exercise in theo lder animals, which may allow for the accumulation of additional strain cycles in older animals. Expand
