Design for various collapse behaviour of sandwich panels subject to in-plane compression
(English)Manuscript (preprint) (Other academic)
Sandwich panels were designed for different collapse behaviour when compressed in the in-plane direction, by altering the material and geometrical properties. An approach previously developed by the authors was used in the design process of the sandwich panels. Panels with CSM glass fibre face sheets of two different thicknesses and two different core materials were studied both numerically and experimentally. The collapse mode of sandwich panels is mainly dependant on the relation between the fracture toughness of the core material and the bending stiffness and strength of the face sheets. By altering properties like the fracture toughness of the core material or the face sheet thickness, the failure mode could be altered. It was shown that the adopted approach can be used in design of sandwich panels for different failure behaviour.
