The article discusses a polyethylene-based metamaterial designed for acoustic control, focusing on the relaxed micromorphic modeling approach. It outlines the significance of fitting parameters to maintain consistency with varying unit cell properties and sizes. The findings include dispersion curves and the effects of geometric characteristics. Ultimately, the study uses a semi-analytical fitting algorithm and numerical values from computational models to demonstrate the efficacy of the relaxed micromorphic model in predicting material behavior. This work stands out due to its analytical nature and comprehensive modeling of metamaterials.
This work emphasizes not just the results of fitting various approaches, but the semi-analytical fitting algorithm and the relaxed micromorphic model's consistency with material properties.
The fitting of the relaxed micromorphic parameters is crucial for understanding metamaterials, particularly how they respond to variations in unit cell size and material properties.
Through defined asymptotes and fitting algorithms, we can achieve numerical fits for material parameters using values obtained via Comsol Multiphysics, highlighting the model's effectiveness.
The study presents a comprehensive examination of dispersion curves and the impact of geometric characteristics on the relaxed micromorphic model's outcomes.
