Flores-Johnson, E. A. and Li, Q. M. (2011) Low Velocity Impact on Polymeric Foams. Journal of Cellular Plastics, 47 (1). pp. 45-63.
The effect of the impactor nose shape on the penetration behaviour of polymethacrylimide (PMI) 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 behaviour of polymeric foams with good agreements between analytical predictions and experimental data.
