TLDR
The results indicate that the mathematical dependency of bone compressive mechanical properties on composition is closely dependent upon the density and mineral content range examined and, in terms of a single compositional measure, is best predicted by apparent ash density expressed as a power function.About:

Trabecular bone modulus–density relationships depend on anatomic site
TL;DR: There is no universal modulus-density relationship for on-axis loading for trabecular bone, and tissue moduli computed using methods that account for inter-site architectural variations did not differ across site, suggesting that the site-specificity in apparent moduli-density relationships may be attributed to differences in architecture.

Dependence of yield strain of human trabecular bone on anatomic site
TL;DR: The results establish that the yield strains of human trabecular bone can differ across sites, but that yield strain may be considered uniform within a given site despite substantial variation in elastic modulus and yield stress.

TL;DR: Results indicate that this sophisticated technique, which is still early in its development, can achieve precision comparable to that of densitometry and can predict femoral fracture load to within -40% to +60% with 95% confidence.

TL;DR: To identify density-elasticity relationships suitable for use in subject-specific FE studies, the development of a benchmark study is proposed, where the elasticity-density relationship is taken as the variable under study, and a numerical model of known numerical accuracy predicts experimental strain measurements.

Modelling bone tissue fracture and healing: a review ☆
TL;DR: The main similarities and differences between normal engineering materials and bone tissue from a structural point of view are demonstrated to demonstrate the importance of computational simulations in biomechanics due to the difficulty of obtaining experimental or clinical results.

TL;DR: These power relationships, which were shown to hold for all bone in the skeleton, allow meaningful predictions of bone tissue strength and stiffness based on in vivo density measurements.

The mechanical behaviour of cancellous bone
TL;DR: The results of this previous study are applied to cancellous bone in an attempt to further understand its mechanical behaviour and the results agree reasonably well with experimental data available in the literature.

The effect of porosity and mineral content on the Young's modulus of elasticity of compact bone.
TL;DR: The Young's modulus of elasticity, the calcium content and the volume fraction (1-porosity) of 23 tension specimens and 80 bending specimens, taken from compact bone of 18 species of mammal, bird and reptile, were determined.

On the dependence of the elasticity and strength of cancellous bone on apparent density.
TL;DR: This paper presents a statistical analysis of the pooled data from a number of previous experiments concerning the dependence of the Young's moduli and strength of cancellous bone tissue upon apparent density and it is concluded that the suggestion of Wolff that compact bone tissue is simply more dense cancellousBone tissue is not an accurate statement.

TL;DR: This relationship between compressive strength and strain rate is applicable to trabecular and compact bone, and provides clinical guidelines for predicting bone strength on the basis of x-ray and densitometric examination.
