Abstract Metamaterials, especially lattice structures, are of great interest for many application areas such as aerospace, automotive and medicine due to their adjustable mechanical properties low weight. Due complex geometry, structures usually manufactured additively, which causes a large variance in the manufacturing-related properties. In order establish metamaterials industrial applications under cyclic loading, fatigue behavior needs be investigated evaluate load capacity these...
Novel cellular materials promise a combination of high strength and low specific weight for sustainable energy‐efficient material design. Inhomogeneities the materials, such as varying coating thickness, are inherent to production process but require advanced characterization in order better understand mechanical properties. Herein, global local acoustic analysis nondestructive thickness on an open‐porous hybrid metal foam system is studied. Experiments numerical simulations carried out...
Vibroacoustic metamaterials offer an approach for the targeted damping of unwanted structural vibrations and noise by integrating periodically arranged resonators into a matrix bulk material. Fabrication using laser bed powder fusion process allows integration depots, leading to extension designable properties. Herein, adaptation acoustic methods is focused on characterization properties metamaterial plates. The investigated vibroacoustic plates are made polyamide PA1.2, combining material...
