| Summary: | Aluminium foams are now being considered for use in lightweight structural sandwich
panels such as aircraft body and in energy absorption systems for protection from impacts. In
both cases, they may be subject to uniaxial and as well as biaxial loadings. In this study, the
uniaxial loading at a rate of 5 mm/min was performed to find the crushing characteristics and
their directional dependency. Eight specimens were used in uniaxial compression. The load
responses were recorded and compared with the biaxial loading. Biaxial tests were conducted
in a custom testing facility between rigid platens, which can be moved independently in two
principles direction at the same speed. Five specimens in biaxial loading in various densities
were used. Considerable enhancement in collapse loads and lead to higher energy absorption
was seen in biaxially loaded metallic foams in comparison with uniaxial loading. The refined
empirical relationship for uniaxial loading was also developed and was satisfactory well with
the experiment. |
