Investigating the potential of micro-focus computed tomography in the study of ancient bone tool function: results from actualistic experiments

摘要: Many experiments have sought to recreate the types of damage that would be expected in ancient stone and bone weapon tips. This is usually presented as visible fractures or microscopic surface modification. Fatigue tests conducted on bovine bones, however, show development internal micro-cracks result from stress, prior actual breakage. In this paper I present results an experimental investigation points subjected a variety activities. assess presence microdamage using micro-focus computed tomography. The two patterns microcracks develop are best viewed longitudinal section. Micro-cracks cumulative feature dependent amount load applied duration activity. When high enough loading rates, will merge together eventually form fracture. Although further needed confirm exact point at which these fatigue begin form, tomography has potential reveal whether individual underwent multiple prolonged impacts thus elucidate probable function/s pointed tools where no apparent. Micro-focus non-destructive non-invasive procedure therefore safe use archaeological artefacts.
