In order to investigate the mechanism of the influence of porosity and pore size on the local mechanical properties of the foam aluminum silicon alloy sandwich panels, the proposed study analyzed the effects of different porosities and different apertures on the local compressive properties and energy absorption characteristics of the foam aluminum silicon alloy sandwich panels. The foam aluminum silicon alloy sandwich panel model was established by C++ and ANSYS, and the finite element simulation was carried out by Abaqus. The results showed that the elastic modulus, yield stress and absorbed energy of the foam aluminum silicon alloy sandwich panels decreased with the increase of porosity under the same pore size. At the same porosity, the modulus of elasticity, yield strength and energy absorption increased with the decrease of pore size.

Key words: sandwich panels, aluminum silicon alloy, localcompression, mechanicalproperties, energyabsorption, finite element analysis
