Injuries induced in high impact events such as anti-vehicle mine blast are an important concern for army forces. This report presents an anatomical finite element model of the neck of a human body in a Light Armoured Vehicle. Importance of neck region has been illustrated in a previous study comparing behaviour of two Hybrid III finite element models with experimental data. The model built here was used to identify which anatomical structures may undergo damages and in what order following a mine blast event. Velocity profile of the torso was simulated based upon results obtained from study mentioned previously with a vertical drop tower. Head and vertebrae were modelled as well as nuchal and anterior longitudinal ligaments. Seven muscles groups were modelled: the trapezius, the levator scapulae, the longissimus, the longus, the scalenus, the splenius capitis and the sternocleidomastoid. Simulation results showed that the anterior longitudinal ligament strain reaches a maximum of 20% in the C7-T1 portion and up to 100% at the C0-C1 level. Simulation results showed also that soft connective tissues experienced important strain rates, as high as 20 000%/s in the higher portion (C0-C1) of the anterior longitudinal ligament.
