Material reaction of diaphyseal bone under torsion. An experimental study on dogs.

The formation of microcracks in entire canine diaphyseal bones under torsional loads was studied. The acoustic emission technique was used to register the stress waves which were generated in the bones by crack formation and/or growth. Acoustic emission signals, characteristic of crack formation and/or growth, were recorded exclusively during the non-linear deformation. This is a strong indication of the elastic behaviour of diaphyseal canine bone material.
