This paper discusses a new superplastically formeddiffusion-bonded SPFDB orthogonally corrugated core sandwich structure and compares its structural behavior with that of a conventional honeycomb core sandwich structure. The stiffness and buckling characteristics of the two types of sandwich structures are compared under conditions of equal structural density. Under certain conditions, the SPFDB orthogonally corrugated core sandwich structure is slightly more efficient than the optimum honeycomb core square-cell core sandwich structure. However, under different conditions, this effect can be reversed. MM
