... modulus of femoral cortical bone. The method is based on a numerical twin of a specific three-point bending test. It has been designed to be reproducible on each test result. In addition, the biofidelity of the geometric acquisition method has been quantified. As the assessment is performed at the scale...

... the mechanical properties of bones have been studied for several decades, the high strain rate data and corresponding material parameters of the rate-dependent constitutive models are still limited. In this study, split Hopkinson pressure bar technique was used to test bovine cortical bones, to obtain the rate...

...Jagjit Singh; N. K. Sharma; M. D. Sarker; Saman Naghieh; Satbir S. Sehgal; Daniel X. B. Chen The fracture properties of cortical bone are directly coupled to its complex hierarchical structure. The limited availability of bone material from many anatomic locations creates challenges for assessing...

... presents our study on the examination of the stress–strain relationship of bovine femoral cortical bone and the relationship representation by employing the Ramberg–Osgood (R–O) equation. Samples were taken and prepared from different locations (upper, middle, and lower) of bone diaphysis and were...

... to assess the time history of the occurrence of AE events during fatigue loading of human tibial cortical bone and to determine the associations between AE variables (energy content of waves, number of AE waveforms, etc.), fatigue life, and bone ash content. Fatigue test specimens were prepared from...

... findings may indicate that although the overall fracture load of the cortical bone has a small affect on the load ratio, it is possible to have local stress concentration points in the trabecular bone based on the load distribution. A detailed investigation of the effect of age-related changes...

...D. Carnelli; D. Gastaldi; V. Sassi; R. Contro; C. Ortiz; P. Vena A finite element model was developed for numerical simulations of nanoindentation tests on cortical bone. The model allows for anisotropic elastic and post-yield behavior of the tissue. The material model for the post-yield behavior...

... internal stresses mechanical strength X-ray diffraction residual stress cortical bone bovine femur hydroxyapatite X-ray diffraction Cortical bone has a hierarchy and composite structure composed of hydroxyapatite (HAp) crystals and collagen fibers in nanoscale. The X-ray diffraction can...

...Giampaolo Franzoso; Philippe K. Zysset The identification of anisotropic elastic properties of lamellar bone based on nanoindentation data is an open problem. Therefore, the purpose of this study was to develop a method to estimate the orthotropic elastic constants of human cortical bone secondary...

..., with the combined effect of 4% increase in porosity and decrease in the cohesive properties reflecting other age-related changes in bone. These results show that intracortical porosity is a significant contributor to the fracture toughness of the cortical bone and that the combination of computational modeling...

...Alexander C. M. Chong; Forrest Miller; McKee Buxton; Elizabeth A. Friis Third-generation mechanical analogue bone models and synthetic analogue cortical bone materials manufactured by Pacific Research Laboratories, Inc. (PRL) are popular tools for use in mechanical testing of various orthopedic...
