What are we doing: 

We do research on the mechanics of metamaterial to develop insight comprehension on how wave modulation occurs due to several periodic alterations of the constitutive unit cell of the metamaterial. Effect of coupling, veering, and locking of various wave modes on the bandgap generation, due to the periodicity, usual attachments or boundary conditions, internal architecture, etc. Extensive study has been performed on the monocouple systems, mass-in-mass (negative mass/inertia) metamaterial, negative stiffness, inertial amplifier, nonlinear and non-reciprocal metamaterial. In addition to the standard bandgap study, we also carried out research on the estimation of overall damping enhancement. Damping enhancement is crucial in mitigating transient responses caused due to extreme events such as storms, earthquakes, blasts, impacts, etc. In parallel to the theoretical advancement, we also make prototypes of metamaterial structures and try to use these in controlling the vibration of various infrastructures. We have designed suitable metamaterials for wind turbine towers, lightweight panel walls, railway pads, piles, and structural sections. Reduced scale lab testing is performed to assess their performance.  We have expertise in formulating spectral element matrices, and obtaining closed-form expressions for vibration control. We also often use machine learning and artificial intelligence for predicting responses or designing and obtaining optimum parameters. 

We also extensively work on the clean and green renewable energy sector. We do research on the analysis and design of offshore  and onshore wind turbine piles and towers, their blades, solar panel mounting structures, etc. Recently exploring the edge-state phenomenon of periodic lattice and inertial amplification we have enhanced the bandgap and energy harvesting level significantly.
