WEIGHT OPTIMIZATION OF STRUCTURAL SANDWICH PANELS.
Abstract
The report covers the application of a simple method, primarily numerical, to the problem of the optimum design of structural sandwich panels of several types and several materials. Compression and shear loading on flat panels and compression on curved panels have been considered. Including variation of panel proportions, four basic cases are studied for four different face materials, two grades of Al alloy, Ti alloy and stainless steel. The core properties assumed are those appropriate to metal honeycomb. The effect of varying core density is allowed for where such variation seems necessary in order to prevent skin wrinkling of the alternative panel designs whose weight is being compared, subject to an assumed overriding minimum practicable density. The weight penalty arising from increase in core stiffness and density above the minimum differs for different face materials. (Author)
