The blast and impact loading of aluminium foam

Investigation on dynamic penetration of closed-cell aluminium foam using in situ deceleration measurement

“…The studies in Refs. [16,20] plotted the normalization of the dynamic plateau stress, s dyn pl =ðr 0 =r s Þ n against impact velocity to investigate dynamic strength enhancement to account for the different densities of the closed-cell aluminium foams. However, it was not considered to be plotted in Fig.…”

Modelling and characterization of cell collapse in aluminium foams during dynamic loading

“…Their main advantage during impact loading is that they transmit relatively low amounts of load due to a unique non-linear plastic deformation process [5,6]. The number of uses for these materials is increasing day by day in applications such as military equipment [7][8][9], automotive parts [10], structural elements and aerospace [4,[11][12][13]. However, little attention has been given to the shockwave attenuation and the energy absorption mechanism of metal foams particularly where the foam has been struck by a projectile [14,15].…”

A two-phase model to simulate the 1-D shock wave propagation in porous metal foam

“…A typical stressestrain curve for metal foams shows three distinct regions [8,10], that are illustrated in Fig. 2.…”
