| Abstract Scope |
Bioinspired metamaterials consist of unique geometries that intend to mimic special types of structural organization found in natural systems. These systems, such as the wing scales of butterflies, diatoms, and nacre, often provide a distinctive set of dispersive properties that can be tuned to manipulate the phononic response. It is well known that phononic materials are highly sensitive to structural variations in geometry and mechanical parameters. To better understand the sensitivity of bio-inspired phononic metamaterials to structural variations, we implement a novel method to compute highly accurate arbitrary order sensitivities of the dispersion relation based on the finite element method and the hypercomplex Taylor series expansion (ZTSE). The sensitivities are calculated from unit representative volumes under Bloch’s periodicity and provide a broader understanding of the behavior of such structures. This work promises to make possible the design of novel bioinspired metamaterials with a higher level of control over their response. |
