Abstract: Meta-materials are artificial materials that perform superior properties in addition to natural behavior. Regardless of their chemical properties, metamaterials show high performance due to their geometric orientation. There are mechanical metamaterials that are used in vibration and acoustic fields, the main subject of which is wave transmission. The propagation of mechanical waves, which can cause problems such as structural damage, fatigue, poor performance, and discomfort in the industry, can be prevented or reduced by using meta-materials. Mechanical waves of various frequencies can be reduced or eliminated by locally resonant metamaterials obtained by adding various masses to viscoelastic materials. Metamaterials can be designed by modifying various lattice structures. Higher performance metamaterials are designed in this study by modifying the lattice structures used in the literature for vibration isolation. Finite element analyzes are carried out to show the transmissibility performance of the designed meta-lattice structures.
