Fracture toughness design in horse hoof keratin.
An engineering fracture mechanics approach was applied to the analysis of the fracture resistance of equine hoof-wall. The relationship between fracture toughness and the morphological organization of the keratin hoof tissue was investigated. Fracture toughness was evaluated using the J-integral analysis method which employs the compact tension test geometry. Tensile tests were also conducted t...
متن کاملNo hoof, no horse! The clinical implications of modelling the hoof capsule.
Horses stand on the tips of their middle fingers and toes. In each forelimb, they bear their weight on an adapted fingernail which forms the hoof wall. This hoof wall is strongly attached to the last bone (third phalanx) which, in turn, is tied into the column of support in such a way that the complex locomotory forces received through the hoof capsule are directed up into the limb in alignment...
متن کاملIsolated pediatric duodenal rupture after horse hoof kick.
An 8 year-old-boy was referred because of abdominal pain 24 hours after being hoof-kicked by a horse in the abdominal wall. On arrival the boy appeared ill, with nausea and vomiting and right abdominal pain. Physical examination revealed epigastric tenderness with muscle guarding in the upper abdominal wall. Because of persistent pain CT was performed and further revealed a very small amount of...
متن کاملFunctional design of horse hoof keratin: the modulation of mechanical properties through hydration effects.
Tensile moduli and J-integral fracture toughness values were determined for horse hoof-wall keratin at four hydration levels. The stiffness of hoof-wall was influenced by water content to a greater degree than is the stiffness of other mammalian hard keratins. Young's modulus increased from 410 MPa at 100% relative hydration (RH) to 14.6 GPa at 0% RH. Fracture toughness was maximal (22.8 kJ m-2...
