Abstract: In order to promote the construction and verification of the finite element models of human thorax and non-lethal projectiles in the field of blunt ballistic impact, the detailed anatomical and analogous structures of the thorax finite element models are combed and five typical of them are compared and verified. The construction and verification methods of the typical non-lethal projectile models are refined and the impact injury assessment methods are summarized. The next research recommendations are given. In order to improve the accuracy and biological fidelity of the thorax model, it is necessary to establish the physical and finite element model on the measurement data of a same cadaver. By revealing the energy interaction between the projectile and the target and the propagation of the stress wave within the target, the direct and remote injury mechanism of the anti-riot kinetic projectile are illustrated.

Key words: finite element method, anti-riot kinetic projectile, blunt ballistic impact, impact injury mechanism
