Sandwich joints with a gap in the core – A systematic examination of the stress distribution

This paper discusses the applicability of the Finite Element Method (FEM) in conjunction with statistical methods in order to examine local effects in the core of sandwich elements. The sandwich elements under consideration are characterized by a gap in the core which induces high local strains in the core. The load case is 3-point bending. The combination of FEM and the Morris method shall serve the purpose of identifying important factors for the design of a joining technology for sandwich elements at an early stage of the development.
