Structural Efficiency Studies of Corrugated Compression Panels with Curved Caps and Beaded Webs.

Abstract

Curved cross sectional elements are employed in new structural concepts for minimum mass compression panels. Corrugated panel concepts with curved caps and beaded webs are optimized by using a nonlinear mathematical programming procedure and a rigorous buckling analysis. These new panel geometries are shown to have superior structural efficiencies compared with known concepts published in the literature. Fabrication of these efficient corrugation concepts has become possible by advances made in the art of superplastically forming of metals. Results of the mass optimization studies of the concepts are presented as structural efficiency charts for axial compression.
