For these structures, two dominant modes of failure in compression can be distiguished. The first one is classical overall buckling and the second one is wrinkling, where only faces buckle while the core remains intact. The main goal of this contribution is the determination of influence of geometry and material properties on the critical load in compression and on the post-buckling behavior (i.e. whether overall buckling or wrinkling occurs). Numerical simulations of the post-peak behavior are carried out for a variety of combinations of material and geometrical parameters. At the end, some pieces of information for the prediction of failure mode and post-peak behavior are given.
