Abstract
In this article, vibration characteristics of sandwich plates with an auxetic honeycomb core and laminated three-phase skin layers subjected to blast load are studied. Higher-order ES-MITC3 element based on higher-order shear deformation theory (HSDT) to achieve the governing equations. The sandwich plates with the ultra-light feature of the auxetic honeycomb core layer (negative Poisson's ratio) and reinforced by two laminated three-phase skin layers. The obtained results in our work are compared with other previously published to confirm accuracy and reliability. In addition, the effects of parameters such as geometrical and material parameters on the vibration characteristics of sandwich plates with an auxetic honeycomb core and laminated three-phase skin layers are fully investigated.
