Abstract Forensic investigation has the primary challenge of assessing cause from limited evidence. To inform the investigation process, computational modelling can assess: i) the potential ballistic pathways, by analysing entry wound and blood spatter patterns; and ii) the influence of target material effects and cranial geometry. The retrograde ejection of blood and tissue following projectile impact from the entry wound is called 'backspatter' and can aid in informing the investigator about the proximity of the shooter, with the potential to differentiate between suicide and homicide. However, the 'backspatter' phenomenon is not well understood. This study presents (i) the development of an anatomically-based model of cranial ballistic injury using the Smoothed Particle Hydrodynamics (SPH) method; (ii) simulation of the tail splashing and temporary cavitation mechanisms by utilizing a range of scalp and bone simulants and comparison with experiment; (iii) evaluation of cranial stress and strain and energy dissipation; and (iv) evaluation of the effects of bullet characteristics on the creation of the entry wound by parametric analysis.
