| Abstract Scope |
In the search for designing novel functionally graded materials, natural models offer unique geometries with special types of structural organization. These natural systems, such as wing scales of butterflies, diatoms, and nacre, often possess distinctive dispersive properties that can be tuned to manipulate the phononic response. Quantifying the sensitivities of the dispersive properties with respect to the different geometrical and material parameters becomes then a powerful tool to reach tunable properties. In this work, we implement a novel method to compute highly accurate arbitrary order sensitivities of the dispersion relation of bio-inspired phononic metamaterials based on the finite element method and the hypercomplex Taylor series expansion (ZTSE). We analyzed unit representative volumes under Bloch’s periodicity and calculated higher order sensitivities with respect to the models’ parameters. The sensitivities aim to provide a broader understanding of the phononic behavior of bioinspired metamaterials and make possible the design of novel structures. |
