Component-Wise Free Vibration Analysis of Sandwich Metamaterials by Carrera Unified Formulation
Erasmo Carrera, Riccardo Augello, Ningning Liu
Abstract. This work presents a free vibration analysis of honeycomb sandwich metamaterial structures with complex cellular cores using the Carrera Unified Formulation (CUF). Three distinct unit cell geometries are investigated within a component-wise (CW) modelling framework. The CUF-based one-dimensional beam approach enables accurate cross-sectional discretization via high-order Lagrange polynomials, offering an efficient balance between computational cost and geometric fidelity for diverse topologies. Convergence studies regarding axial and cross-sectional mesh refinements are conducted, highlighting the error reduction trends across different core configurations. Results show that the proposed methodology achieves rapid convergence and captures the essential vibrational characteristics of metamaterial panels, validating it as a flexible and robust platform for the hierarchical modelling of architected materials.
