A sandwich structure typically consists of two facesheets separated by lightweight core. Buckling is one of the critical failure modes for sandwich structure in particular for relatively large panels. A sandwich can be treated as a laminate where the core is just another ply with negligible stiffness and strength properties and thickness equal to the core thickness. Buckling is one of the critical failure modes for sandwich structure in particular for relatively large panels. The reason is that it is hard to design against all possible failure modes in the post‐buckling regime and, as a result, buckling is usually considered to coincide with final failure. Wrinkling is a local buckling phenomenon where the facesheet of a sandwich buckles over a characteristic half‐wavelength l, which is unrelated to the overall length or width of the panel. This chapter also discusses sandwich intracellular buckling under compression and attaching sandwich structures.
