A study of the progression of damage in an axially loaded Branta leucopsis femur using X-ray computed tomography and digital image correlation
This paper uses X-ray computed tomography to track the mechanical response of a vertebrate (Barnacle goose) long bone subjected to an axial compressive load, which is increased gradually until failure. A loading rig was mounted in an X-ray computed tomography system so that a time-lapse sequence of...
