... structures Lattice structures Quasi-static Experimental analysis Fused deposition modelling Polylactic acid (PLA) Auxetic materials, distinguished by having a negative Poisson’s ratio, display unusual mechanical properties, including lateral expansion when subjected to tension and contraction...

... critically re-examined during the selection phase. Findings The literature on the energy absorption capabilities of cellular solids is rapidly growing, with particular emphasis on metallic materials fabricated via laser powder bed fusion, primarily tested under quasi-static loading conditions. Although...
