The paper presents a numerical model, which allows one to determine the wrinkling stress in sandwich panels. The wrinkling of the compressed face of sandwich panel can be caused by a bending moment or axial force. The developed model enables one to take into account various boundary conditions and micro-profiling of sandwich faces. Damage initiation and propagation in the interface between the face and the sandwich core is defined, too. The numerical procedures and parameters of the FE model are discussed. The obtained solutions are related to the results of actual experiments.
