TL;DR: In this paper, the buckling of thick sandwich panels with orthotropic elastic face sheets bonded to a linear elastic orthotropic core was studied and it was shown that large errors can be incurred in computing buckling loads with available commercial software, unless the proper work conjugate measures of stress and strain with their stress-dependent tangential moduli are used.

TL;DR: In this article, the elastic constants for a C-core sandwich panel are summarized and the results obtained from thick plate bending analysis utilizing these constants, are found to be in excellent agreement with the full 3-D finite element analysis.
Abstract: Sandwich plate decking, consisting of two facing plates separated by a core of stiffeners, is known to possess high strength and high stiffness to weight ratios. This form of construction is appropriate for structures where the self weight is one of the governing design criteria. This is particularly applicable in the design of offshore accommodation modules to facilitate onshore or offshore installation. The self weight could be reduced while the strength is maintained. In this paper, the elastic constants for a C-core sandwich panel are summarized. In particular, the explicit expression representing the shear stiffness in the weaker direction is derived. Numerical examples are presented and the results obtained from thick plate bending analysis utilising these constants, are found to be in excellent agreement with the full 3-D finite element analysis. In comparison to the finite element analysis, the computation effort for the thick plate bending model is significantly smaller.

TL;DR: In this paper, a WBK-cored sandwich panel under compression and shear was evaluated in more detail by experiment and finite element (FE) simulation, and the model optimally designed on the basis of the analytic solutions gave the expected results.
