Modelling, Volume 7, Issue 4

2026 August - 54 articles

Cover Story: Additive manufacturing has enabled the widespread fabrication of lattice mechanical metamaterials, but the resulting structures inevitably deviate from their nominal designs. Because their wave attenuation performance relies on accurately predicted phononic bandgaps, understanding the sensitivity of dispersion analyses to geometric and modelling discrepancies is critical. This work investigates how finite element modelling errors affect the predicted dispersion behaviour of lattice metastructures. The results identify the most critical sources of error and provide practical guidelines for reliable simulations, while offering qualitative insight into how geometry-related imperfections may influence the dynamic response of manufactured metamaterials. View this paper
