TLDR
In this paper, a multilayered pyramidal lattice structure constructed from stainless steel was investigated and the lattice was fabricated by folding perforated 304 stainless steel sheets and bonding them to thin intervening sheets using a transient liquid-phase bonding technique.About:

Overview of transient liquid phase and partial transient liquid phase bonding
Grant O. Cook,Carl D. Sorensen +1 more
TL;DR: Partial transient liquid phase (PTLP) bonding as discussed by the authors is a variant of TLP bonding that is typically used to join ceramics and has found many applications, most notably the joining and repair of Ni-based superalloy components.
Journal ArticleDOI
Dynamic crushing and energy absorption of regular, irregular and functionally graded cellular structures
TL;DR: In this paper, the in-plane dynamic crushing of two-dimensional honeycombs with both regular hexagonal and irregular arrangements was investigated using detailed finite element models, and three distinct crushing modes for honeycomb with a constant relative density: quasi-static, transition and dynamic.
Journal ArticleDOI
The blast resistance of sandwich composites with stepwise graded cores
TL;DR: In this paper, two types of core configurations, with identical areal density, were subjected to the shock wave loading, and the results showed that configuration 1 outperformed configuration 2 in regards to their blast resistance.

Experimental and numerical study of foam filled corrugated core steel sandwich structures subjected to blast loading
TL;DR: In this article, the influence of foam infill on the blast resistivity of corrugated steel core sandwich panels was investigated experimentally using a shock tube facility and high speed photography and numerically through Finite Element Methods (FEM).

Journal ArticleDOI
Fabrication and structural performance of periodic cellular metal sandwich structures
TL;DR: The authors showed that truss and textile cores are superior to honeycombs at low relative densities, because of their superior buckling resistance and lower manufacturing cost as well as their multifunctionality.

The Resistance of Clamped Sandwich Beams to Shock Loading
Norman A. Fleck,Vikram Deshpande +1 more
TL;DR: In this article, the structural response of the sandwich beam is split into three sequential steps: stage I is the one-dimensional fluid-structure interaction problem during the blast loading event, and results in a uniform velocity of the outer face sheet; during stage II the core crushes and the velocities of the faces and core become equalized by momentum sharing; stage III is the retardation phase over which the beam is brought to rest by plastic bending and stretching.

Blast and ballistic loading of structures
John Hetherington,Peter N. Smith +1 more
TL;DR: In this paper, the authors introduce the concept of explosives and discuss the structural response of a system to a ballistic attack against buried structures and buried structures, as well as their application in the field of protection against ballistic attack.

Collapse of truss core sandwich beams in 3-point bending
Vikram Deshpande,Norman A. Fleck +1 more
TL;DR: In this paper, the macroscopic effective stiffness and strength of triangulated face-sheets and tetrahedral core are estimated by idealizing them as pin-jointed assemblies; tests show that this approximation is adequate.
