Title of Paper:

Blast Resistance of Sandwich-Walled Hollow Cylinders with Graded Metallic Foam Cores

Journal:

Composite Structures

Summary:

The dynamic responses and blast resistance of all-metallic sandwich-walled hollow cylinders with graded
aluminum foam cores are investigated using finite element simulations, and compared with those of
conventional ungraded ones. After validating the numerical approach and introducing the computational
model, sandwich-walled hollow cylinders with various graded aluminum foam cores are analyzed under
air blast loading. It is demonstrated that the radial deflection of graded cylinders is smaller than and the
blast resistance superior to that of ungraded ones when subjected to identical air blast loading. This can be
further improved by optimizing the foam core arrangement. Finally, the influence of face-sheet arrangements
on the dynamic behavior of graded cylinders is explored.
