"Development of biomechanical response corridors of the thorax to bluntballistic impacts" (Bir, C., Viano, D., King, A., 2004, Journal of Biomechanics37, 73-79.) contains apparent measurement errors. Areas under several force vs.time (Fig. 2) and force vs. deflection curves (Fig.4) differ significantly fromthe momentum and kinetic energy changes, respectively. These differencesviolate Newton's second law and the work-energy theorem.
