ABSTRACT: Impact analysis is process of analyzing impact of a base object by a projectile that may be affected by plastic deformation. This requires a software representation model that can formalize the knowledge about the various dependencies between impacting objects. This study was carried out with the aim of objectively assessing whether a honeycomb structure is better structurally compared to conventional engineering materials. Honeycomb structures have relatively high compression and shear properties out-of-plane while having a low density, implying presence of very high specific strengths. So these materials find wide application in aerospace industry. Explicit dynamics tool of Ansys for impact analysis, was used to implement different impact approaches. Different materials were analyzed for failure at various impact velocities and base plate thickness as well as impact angles for suggesting superior honeycomb structural properties from impact analysis results.
