Abstract

The present investigation examines the interaction of shock wave with the aluminum closed cell foam experimentally using shock tube. Shock tube experiments are carried out for different thicknesses of the foam. Effect of foam thicknesses and foam relative density is studied for shock wave attenuation and/or enhancement. Results in terms of incident and reflected shock pressure time histories are obtained and compared for its effectiveness with the absence and presence of the foam under shock loading. Results from the present investigations show that foam density and foam thickness has the most significant effect on the peak reflected shock pressure time histories. The primary objective of this study is to investigate the behavior of the closed cell aluminum foam under shock wave to be used as sacrificial layer in blast protection. It is concluded that the closed cell aluminum metal foam can effectively be used as sacrificial layer in blast protection of structures.
