Bone Tissue Properties: intervertebral_disc
Mechanical properties of biological tissues for biomedical engineering and orthopaedic design: cortical bone (longitudinal, transverse, torsion, fatigue), cancellous/trabecular bone (low/medium/high density), articular cartilage (compressive, tensile, shear), fibrocartilage/meniscus, tendon, ligament, intervertebral disc (annulus fibrosus, nucleus pulposus), skin, and arterial wall. Properties include elastic modulus, ultimate tensile/compressive strength, yield strength, ultimate strain, Poisson ratio, and fatigue limit as min/typical/max ranges.
| tissue type | loading direction | elastic modulus GPa max (GPa) | elastic modulus GPa min (GPa) | elastic modulus GPa typical (GPa) | fatigue limit MPa min (MPa) | poisson ratio max (dimensionless) | poisson ratio typical (dimensionless) | tissue description | yield strength MPa max (MPa) | yield strength MPa min (MPa) | yield strength MPa typical (MPa) |
