A sandwich panel is a lightweight structure, economical and having low thermal conductivity. It is made up of three layers in which the middle layer is called core which is bounded with thin layers at top and bottom called faces. Generally, the core has relatively low-density which makes it lightweight. The buckling load analysis of sandwich panel having isotropic core and orthotropic faces is studied for different support conditions using the FE based software ABAQUS. The FE model is validated with suitable published results. Then it is used to find critical buckling load of sandwich panel with isotropic core and orthotropic faces. Many new results have been presented for different thickness, end conditions, aspect ratio, etc.
