Mineralized Collagen Fibrils: A Mechanical Model with a Staggered Arrangement of Mineral Particles [PDF]

open access: yesBiophysical Journal, 2000
Both elastic modulus and fracture stress are known to increase with the amount of mineral deposited within collagen fibrils. Current mechanical models of mineralized fibrils, where mineral platelets are arranged in parallel arrays, reproduce the first effect but fail to predict an increase in fracture stress.
