Bone Mechanics
The study of mechanical structural behavior, anisotropy, and remodeling of bone tissue under physical loads.
Governing formula
Stress σ = F / A, Young's Modulus E_cortical ≈ 18 GPa
SI unit
MPa / GPa (Tensile & Compressive Strength)
In depth
Bone is a composite material composed of flexible collagen fibers embedded in hard hydroxyapatite mineral crystals. Wolff's law dictates that bone remodels dynamically along lines of mechanical stress.
Examples in the real world
Cortical bone exhibiting high compressive strength (~190 MPa) compared to porous trabecular cancellous bone.
