The use of foam has the potential for energy absorption enhancement.
Many types of materials can be produced in the form of foams, including
metals and polymers. Of the metallic based foams, aluminium based
are among the most advanced. Aluminium foams couple good specific
mechanical properties with high thermal stability. Among the various
aspects still to be investigated regarding their mechanical behaviour
is the influence of a hydrostatic state of stress on yield strength.
Unlike metals, the hydrostatic component affects yields. Therefore,
different loading conditions have to be considered to fully identify
the material behaviour. Another important issue in foam structure
design is the analysis of composite structures. The mechanical behaviour
of an aluminium foam has been examined. The foam was subjected to
uniaxial, hydrostatic stress, pure deviatoric stress, and combinations
thereof. Results obtained will be presented as quasi-static and dynamic
uniaxial compression and quasi-static bending and shear loading.
Moreover, composite structures were made by assembling the foam into
aluminium cold extruded closed section 6060 aluminium tubes. The
results show that the energy absorption capability of the composite
structures is much greater than the sum of the energy absorbed by
the two components, the foam and the tube.
