Nonlinear 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 کاملLinear 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 کاملAnalysis of Fatigue Damage in Bovine Trabecular Bone
INTRODUCTION Cyclic loading of trabecular bone can lead to fatigue damage and increased risk of fracture in both young and the elderly populations. Fatigue damage processes in trabecular bone include reduction of elastic modulus and accumulation of residual strain. Development of models relating the above effects to the loading variables (stress, strain) is essential for a predictive understand...

متن کاملExperimental and numerical characterisation of the elasto-plastic properties of bovine trabecular bone and a trabecular bone analogue.
The inelastic pressure dependent compressive behaviour of bovine trabecular bone is investigated through experimental and computational analysis. Two loading configurations are implemented, uniaxial and confined compression, providing two distinct loading paths in the von Mises-pressure stress plane. Experimental results reveal distinctive yielding followed by a constant nominal stress plateau ...
