MINIMUM WEIGHT ANALYSES AND DESIGN PROCEDURES FOR FLAT, TRUSS-CORE SANDWICH PANELS

摘要

Minimum weight analyses and design charts are developed for truss-core sandwiches acting as compression panels, wide columns, and shear panels. The analyses account for the load-carrying ability of the core in all cases and the effects of trans-verse shear stiffness and plasticity in the first two cases. It is shown that in ranges of loading and material properties where truss-core sandwiches have their greatest applicability, transverse shear stiffness has negligible effects. Examples of problems are given.
