Abstract:

To investigate the vibration suppression performance of metaconcrete under blast loading, a three-dimensional finite element model of metaconcrete measuring 100 cm×100 cm×30 cm was established based on the theory of locally resonant metamaterials. The Arbitrary Lagrangian-Eulerian (ALE) method was employed to simulate TNT blast loading, and the effects of material properties, geometric dimensions, and non-uniform distribution of resonant aggregates on the vibration suppression performance of metaconcrete were systematically analyzed. The results show that metaconcrete can effectively attenuate blast-induced stress waves through local resonance. Within the parameter ranges studied, the elastic modulus of the coating has the most significant influence on the peak vibration velocity, while none of the parameters show a statistically significant effect on the peak stress. The bottom-enriched distribution of resonant aggregates does not degrade the overall vibration suppression performance; instead, a periodic arrangement exhibits superior overall performance due to the combined effects of local resonance and Bragg scattering. A four-layer resonant aggregate structure with optimized parameters achieves 93.5% attenuation rate of impact energy. This study provides theoretical references for material selection, parameter design, and process control in metaconcrete.
