The paper concerns the phenomenon of wrinkling of compressed facing of a sandwich panel. The parametric analysis of the numerical model of the sandwich panel with a soft core is presented. The core was assumed as an elastic orthotropic material. The results of numerical simulations show the sensitivity of a sandwich structure to the variations of the core parameters. The results are evaluated qualitatively and quantitatively.
