Fracture of bone tissue: The 'hows' and the 'whys' (2008)
Journal Article
Gupta, H. S., & Zioupos, P. (2008). Fracture of bone tissue: The 'hows' and the 'whys'. Medical engineering & physics, 30(10), 1209-1226. https://doi.org/10.1016/j.medengphy.2008.09.007

The mechanical performance of bone is of paramount importance for the quality of life we experience. The structural integrity of bone, its hierarchical structure, organisation and its physicochemical constitution, all influence its ability to withsta...

Microcracking damage and the fracture process in relation to strain rate in human cortical bone tensile failure (2008)
Journal Article
Zioupos, P., Hansen, U., & Currey, J. D. (2008). Microcracking damage and the fracture process in relation to strain rate in human cortical bone tensile failure. Journal of biomechanics, 41(14), 2932-2939. https://doi.org/10.1016/j.jbiomech.2008.07.025

It is difficult to define the 'physiological' mechanical properties of bone. Traumatic failures in-vivo are more likely to be orders of magnitude faster than the quasistatic tests usually employed in-vitro. We have reported recently [Hansen, U., Ziou...

Fatigue strength of human cortical bone: Age, physical, and material heterogeneity effects (2008)
Journal Article
Zioupos, P., Gresle, M., & Winwood, K. (2008). Fatigue strength of human cortical bone: Age, physical, and material heterogeneity effects. Journal of biomedical materials research. Part A, 86(3), 627-636. https://doi.org/10.1002/jbm.a.31576

Human bone is highly heterogeneous at the microscale and this heterogeneity has been thought to relate to some fracture scenarios. The fatigue strength of cortical bone has been shown to relate to its inner architecture (osteonal or fibrolamellar) an...

Using Risk Factors and Quantitative Ultrasound to Identify Postmenopausal Caucasian Women at Risk of Osteoporosis (2008)
Journal Article
Minnock, E., Cook, R., Collins, D., Tucker, J., & Zioupos, P. (2008). Using Risk Factors and Quantitative Ultrasound to Identify Postmenopausal Caucasian Women at Risk of Osteoporosis. Journal of Clinical Densitometry, 11(4), 485-493.e3. https://doi.org/10.1016/j.jocd.2008.04.002

There is a need to prescreen large numbers of individuals for osteoporosis due to current demands on clinical resources. Some previous attempts to predict individuals at risk have used simple indices based on patient information, or Quantitative Ultr...

Some basic relationships between density values in cancellous and cortical bone (2008)
Journal Article
Zioupos, P., Cook, R. B., & Hutchinson, J. R. (2008). Some basic relationships between density values in cancellous and cortical bone. Journal of biomechanics, 41(9), 1961-1968. https://doi.org/10.1016/j.jbiomech.2008.03.025

Density is a salient property of bone and plays a crucial role in determining the mechanical properties of both its cancellous and cortical structural forms. Density is defined in a number of ways at either the bone tissue (Dapp, apparent) or the bon... Read More about Some basic relationships between density values in cancellous and cortical bone.

The effect of strain rate on the mechanical properties of human cortical bone (2008)
Journal Article
Hansen, U., Zioupos, P., Simpson, R., Currey, J., & Hynd, D. (2008). The effect of strain rate on the mechanical properties of human cortical bone. Journal of Biomechanical Engineering, 130(1), Article 011011. https://doi.org/10.1115/1.2838032

Bone mechanical properties are typically evaluated at relatively low strain rates. However, the strain rate related to traumatic failure is likely to be orders of magnitude higher and this higher strain rate is likely to affect the mechanical propert...
