Damaru inspired lattice metastructure
IIT Kanpur researchers have demonstrated how, with a micro-structured hourglass-shaped metastructure in the lattice unit, one can get a wider variation of propagation and stop bands. The hourglasses are developed in the IIT Kanpur Smart Materials Laboratory using additive manufacturing.
This has wide applications in the field of vibration isolation in high-speed trains, stealth submarines and helicopter rotors.
