“…The through-thickness core coordinate z is measured upwards from the lower face-core interface. Load P ¼ 13.9 N (see Figure 21) [33] increasing difference between the lines z ¼ 5 and z ¼ 35. There is also a very good agreement between the measured displacements and displacements found using the high-order theory.…”

“…In order to validate the model predictions based on the nonlinear high-order sandwich theory (and the geometrically nonlinear FEA results), an experimental investigation was conducted. As the actual changes of thickness are very small we chose to apply ESPI [33]. The ESPI system described in the previous section 'sandwich plates with inserts' was used.…”

The objective of the paper is to provide an overview of the mechanical effects, which determine the occurrence and severity of localised bending effects in sandwich structures, and to provide a survey of the available structural sandwich models, with special emphasis on their ability to describe local bending effects. The presentation includes a brief survey of the various structural models, including classical, ‘first‐order shear’, ‘high‐order’ and continuum mechanics‐based models. Moreover, the paper focuses on and addresses the experimental characterisation and assessment of local effects in sandwich structures based on realistic engineering practice, examples including sandwich panels with core materials of different stiffness (core junctions), sandwich plates with inserts and junctions between sandwich panels of different curvature. The issues of general load response (global and local) as well as failure and fatigue of such sandwich structures subjected to out‐of‐plane and in‐plane loads are discussed in some detail, with the inclusion of recent theoretical and experimental results.
