Modeling of Lattice Structures Energy Absorption under Impact Loads

Lattice structures are promising design solutions for lightweight components in many industrial fields as aeronautics and space. The multifunctional design approach aims to combine in the same component several capabilities, including the ability to absorb impact energy with high efficiency. The additive manufacturing of metals is presently opening to innovative constructive approaches where static strength, lightweight and impact behavior must be considered together in design and simulation. This paper introduces the modeling results of the energy absorbed by different lattice cells topologies under impacts.
