Comparative computational study of composite sandwich panels with varying auxetic core topologies and orientations subjected to air blast loading

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

A preliminary computational study has been conducted which investigates the dynamic response of sandwich panels with cores constructed of varying cellular topologies subjected to air blast loading. Six different cells were selected for comparison. Of these, the hexagonal cell represents a conventional core topology, whereas the other five are “auxetic” geometries with negative Poisson's ratios. Following the application of a blast load, the double-arrowhead core geometry produced the lowest peak deflection.
