Numerical and experimental study on mechanical behaviour of the AlSi10Mg aluminium structures manufactured additively and subjected to a blast wave

The paper is related to energy absorptive properties of additively manufactured metallic cellular structures. samples Honeycomb, Auxetic, rhomboidal Lattice and a regular Foam are subjected dynamic compression due the blast tests. cuboidal by Direct Metal Laser Sintering (DMLS) method using AlSi10Mg aluminium powder. experimental tests performed means an Explosive Driven Shock Tube (EDST). measured results transmitted forces in relation shortening allow analyse deformation processes each selected geometry. In addition, evaluation structural responses leads identification structure properties, such as equivalent stress over strain or absorption per unit mass. Moreover, process modelled numerically explicit code LS-DYNA R9.0.1. obtained simulations provide complete analysis experimentally observed mechanisms.
