Sažetak
Aluminium foam is, principally, a composite material consisting of aluminium or aluminium alloy matrix and of pores filled up with a gas distributed throughout the matrix. Foamed materials in general, and aluminium foams in particular, demonstrate a number of interesting properties due to their porous structure, which makes them usable in a wide range of applications. Under compression, foamed materials show a unique stress – strain response with a plateau region in which the stress is nearly constant over a wide range of strain. In this paper, several samples of closed cell aluminium foams were produced from an Alulight AlMgSi 0, 6 TiH2 - 0, 4 precursor. The compressive deformation was examined using universal test machine. The strain rate was 10-3 s-1 and 10-2 s- 1. Results show that the stress-strain curves depends on strain rate in a range of quasi-static compression and curves are similar but not overlapping. The higher speed tests have less expressed and lower value of the plateau stress.
