Bone and Fracture Mechanics Orthoteers (Visit this link)
Bone can be considered as a biphasic composite material, mineral as one phase, and collagen and ground substance as the other The combined substances are stronger for their weight than either substance alone Cortical bone is stiffer than cancellous bone and more brittle, withstanding less strain before failure than cancellous bone * Fracture occurs in cortical bone in vitro at strains of only 2% * Fracture occurs in cancellous bone in vitro at strains of> 75% Bone is VISCOELASTIC (= time dependent property where the deformation of the material is related to the rate of loading, hysteresis, creep, stress relaxation)
