Analysis of Corrugated Core Sandwich Panels

The demand for light weight sandwich panels are becoming increasingly important as multi-functional components in many areas. The tremendous need of these light weight modular structures have application in bridge deck slabs, partition walls, roof slabs etc. Corrugated core sandwich panels are composite structures in which a corrugated core is sandwiched between a top and bottom face sheets. One of the main characteristics is their high stiffness to mass ratio under bending conditions and also good impact resistance. This study mainly focuses on the analysis of corrugated core sandwich panels, wherein, investigation is performed to determine the effect of geometric parameters on the mechanical behavior of the corrugations on the panel by utilizing different materials. Static, dynamic and buckling analyses of corrugated core panels were conducted and its applicability in bridge deck were presented. The studies were performed using ANSYS 16. The use of different types of core shapes exhibited a variation on deformation and shear force of the panels along witth the performance of panels on different loading condition. Transient analysis were done to determine the effect of moving loads and the results thus obtained from the study revealed that z core corrugated sandwich panel shows less deformation and more stress compared to other shapes.
