9 Damaged Metamaterials: Structural Health Monitoring and Damage Tolerance 81 Fig. 9.6 Damage index δj corresponding to the intact, slightly damaged, and heavily damaged metastructures, when using ω1 and ω2 corresponding to the first bandgap. The slight damage and heavy damage exist at P15 Fig. 9.7 Difference between δj corresponding to the intact metastructure and that corresponding to the slightly damaged and heavily damaged metastructures, when using ω1 and ω2 corresponding to the first bandgap. The slight damage and heavy damage exist at P15 Fig. 9.8 Damage index δj corresponding to the intact, slightly damaged, and heavily damaged metastructures, when using ω1 and ω2 corresponding to the second bandgap. The slight damage and heavy damage exist at P15 Fig. 9.9 Difference between δj corresponding to the intact metastructure and that corresponding to the slightly damaged and heavily damaged metastructures, when using ω1 and ω2 corresponding to the second bandgap. The slight damage and heavy damage exist at P15
