influence of material’s anisotropy of elastic or/and plastic regimes on direction-dependent properties of cortical bone obtained by means of indentation such as elastic moduli and hardness as well as to study the size effect phenomenon. To achieve this, a three-dimensional finite element model of micro-indentation was developed. It should be emphasizedCited by: 5. The influence of matrix anisotropy will be discussed in a forthcoming paper. Strictly speaking, bone is a poroelastic material and therefore a relevant framework with which to study the effective behaviour of the medium is that presented by Cowin () who applied the classical Biot poroelasticity theory to study deformation driven fluid Cited by: Purpose: The purpose of this study is to investigate the effect of anisotropy of cortical bone tissue on measurement of properties such as direction-dependent moduli and hardness. Anisotropy in the compressive mechanical properties of bovine cortical bone and the mineral and protein constituents. Anisotropy in the compressive mechanical properties of bovine cortical bone and the mineral and protein constituents.
Note that these ARs are lower than actual anisotropy in cortical bone since in the present work the bony matrix anisotropy has been neglected; the latter has a significant influence on cortical bone anisotropy, as was pointed out by Crolet et by: Thus, the size and shape of the bone, as well as the properties of the bone tissue influence structural properties. In contrast to the structural behavior, the material behavior, or material properties, of bone tissue is independent of the specimen geometry. However, a deeper comprehension of bone anisotropy could help understand the basic mechanical properties of mouse cortical bone. The aim of this study is to shed light on the micromechanical properties along the longitudinal and transverse directions in the mouse femoral shaft and to determine a relationship between by: 9. properties of bone, such as the post-yield deformation and work to fracture [5,12,13,2S]. Also, recent studies have demonstrated that age-related reductions in the toughness of bone correlates significantly with changes in the integrity of the collagen network in bone (e.g., collagen denaturation and cross-links) [29,30].

elastoplastic material. In this study, a constitutive model of cortical bone considering anisotropic inelasticity and damage evolution was developed to predict injuries more accurately. The new model can satisfactorily represent mechanical properties of cortical bone including anisotropy of elastic modulus and yield stress withCited by: 1. The influence of bone anisotropy with respect to principal stress/strain distribution on human femur external surface was accessed through the use of analytical and finite element approaches. The models results show that the principal angles at a medial path bone surface have a good correlation with human femur bone lamellae angles. The bone properties is dependent on the morphology of bone, bone tissue properties and bone volume fraction in microscopic scale - . However, most of the studies of OI bone . The mechanical properties of bone are affected by cross-linking of the organic matrix , , which is an ultrastructural phenomenon. Ultrastructure and Microstructure and Effects On Mechanical Properties. The mechanical properties of bone seen in the force displacement examples are expressions of the mechanical properties of the hard by: 1.
