Finite element study of high-speed blunt impact on thorax: linear elastic considerations

This paper investigates the response of an idealized three-dimensional model of thorax to pressure impulses of duration T in the range 50200 μs the TW bends under the localized load. In the lung, it is manifest that the energy is carried by a wave. Velocity at the lung surface (which is a possible injury criterion) is driven by the motion of the TW. Results indicate that for 50
