Linear viscoelasticity - bone volume fraction relationships of bovine trabecular bone
Trabecular bone has been previously recognized as time-dependent (viscoelastic) material, but the relationships of its viscoelastic behaviour with bone volume fraction (BV/TV) have not been investigated so far. Therefore, the aim of the present study was to quantify the time-dependent viscoelastic behaviour of trabecular bone and relate it to BV/TV. Uniaxial compressive creep experiments were p...
متن کاملCombination of topological parameters and bone volume fraction better predicts the mechanical properties of trabecular bone.
Trabecular bone structure may complement bone volume/total volume fraction (BV/TV) in the prediction of the mechanical properties. Nonetheless, the direct in vivo use of information pertaining to trabecular bone structure necessitates some predictive analytical model linking structure measures to mechanical properties. In this context, the purpose of this study was to combine BV/TV and topologi...
متن کاملNonlinear viscoelastic characterization of bovine trabecular bone
The time-independent elastic properties of trabecular bone have been extensively investigated, and several stiffness-density relations have been proposed. Although it is recognized that trabecular bone exhibits time-dependent mechanical behaviour, a property of viscoelastic materials, the characterization of this behaviour has received limited attention. The objective of the present study was t...
متن کاملMultiaxial Viscoelasticity and Damage Effects in Vertebral Trabecular Bone
INTRODUCTION: The rapid expansion of the at-risk population for pathological fracture has led to increased interest in the ability to predict the mechanical behavior of trabecular bone as it relates to routine nontraumatic loading. A large body of work has established that the mechanical behavior of cancellous bone, particularly stiffness and strength under monotonic loading, is strongly depend...
متن کاملBone volume fraction and fabric anisotropy are better determinants of trabecular bone stiffness than other morphological variables.
As our population ages, more individuals suffer from osteoporosis. This disease leads to impaired trabecular architecture and increased fracture risk. It is essential to understand how morphological and mechanical properties of the cancellous bone are related. Morphology-elasticity relationships based on bone volume fraction (BV/TV) and fabric anisotropy explain up to 98% of the variation in el...
