A Simplified Thick Plate Analogy for the Analysis of All-Steel Sandwich Panels

An all-steel sandwich punel consists of two steel facing flat plates spot-welded onto a core of stiffeners, which may consist of zed sections, tophats, channels, or corrugated sheeting. Such panels have been studied extensively, and both numerical and analytical comparisons have been reported. This paper presents a modified thick plate approach for the analysis of snndwich panels. To better appreciate the development of the proposed method, a brief review of the previous modelling techniques - i.e. closed-form solution, grillage analogy and the conventional finite element modelling - is given.
