Abstract

An analytical modelling of symmetrical wrinkling is proposed : from original assumptions on displacements within the core, and from an energy minimisation method, it is possible to predict critical loads and buckling modes better than traditional models do, and to distinguish the influence of each structure component. Compression tests were carried out on sandwich structures to validate the model. A FE analysis has been achieved in parallel : a fine modelling allows to find results close to experimental ones.
