Abstract

Sandwich panels consist of two face sheets connected by a relatively low-density core result in high strength and stiffness, which lead promising design advantages. Steel sandwich panels offer substantial resistance to static and dynamic loads due to their high stiffness and substantial energy absorbing capacity. Panels of this kind are interest of potential use in ships, building, and bridge structures especially in extreme environments, accidental or terrorist blasts. Adequately designed structural sandwich panels are required to perform under such conditions due to that this research is conducted to investigate the mechanical behavior of steel sandwich panels using finite element analysis techniques and experimental test methods. A verification study performed accurately based on former research and conventional numerical and finite element analysis methods are successfully applied to the current study. Finite element analyses are then verified with experimental test procedures using Linear Variable Displacement Transducers (LVDTs) and strain gages. Sophisticated photogrammetry techniques are also used to visualize the mechanical response of sandwich connection panels
