The effect of the impactor nose shape on the penetration behavior of
polymethacrylimide foams is investigated in the velocity range of 4—8 m/s. It
is observed from experimental results that penetration load depends on the geometry
of the impactor and the density of the foam. An analytical model is developed to
predict the penetration behavior of polymeric foams; good agreement between
analytical predictions and experimental data is obtained.
