The element formulation utilizes a v.~Kármán type multilayer theory, adopting the discrete Kirchhoff approach for the contribution of the face sheets and a simplified three-dimensional formulation for the core. The discretized nonlinear problem is solved by the Newton-Raphson method.enfinites ElementSandwich-Bauweisegroße DeformationInstabilitätDeckschichtknitternKernkompressibilität531620conference paper
