Performance evaluation of Reinforced honeycomb structure under blast load

Abstract: In this study, numerical simulations were carried out to explore the response of the reinforced honeycomb sandwich structure with varying cell size (7, 10 and 15 mm), node length (25, 37.5 and 50 mm) and cell wall thickness (0.1, 0.2, 0.3 and 0.4 mm). The honeycomb structure made of aluminum alloy 8011 were subjected to low intensity blast loads by varying mass of TNT (10 g, 15 g, 20 g and 25 g) and standoff distance (200 mm, 250 mm and 300 mm). Commercial finite element code LS-DYNA was employed to carry out … Show more

“…Because of environmental effects, a part of the sandwich structure could be damaged. Also, as a consequence of the application field where sandwich structures are used, they are mostly under dynamic loadings [6]. Therefore, it is important to study and evaluate the dynamic characteristics of sandwich structures under the assumption that the sandwich structure has undergone debonding.…”
