Microstructural parameters affecting the compressive response of closed-cell aluminum foams
Enrique Prados Martín
Abstract
Closed-cell aluminum foams are gaining widespread acceptance, especially in automotive, aviation and defence sectors, by virtue of their high strength-to-weight ratio, good energy absorption performance and affordable manufacturing costs, which makes them a shock absorber material with enormous potential. Microstructural parameters such as cell size, cell aspect ratio, cell wall thickness variation, cell wall geometry and cell shape irregularity, have a by no means negligible influence on the compressive response of closed-cell aluminum foams. The most recent studies, both experimental and numerical, on the macroscopic properties-microstructure relationship are scrutinized and their results are discussed in this work.
