Analysis and applications of melt expulsion during ultrasonic vibration-assisted laser surface processing
Alavi, Seyyed Habib (2018-05)Simultaneous application of ultrasonic vibrations during conventional material processing is recently gaining widespread attention due to enhancement of material removal mechanism and improvement in metallurgical quality. ... -
Development of Lightweight, Compact, Structurally-integrated Acoustic Liners for Broadband Low-frequency Noise Mitigation
Chambers, Andrew Thomas (2017-05-01)Airborne noise with a low dominant frequency content (<~500 Hz) has detrimental effects in many applications, but is as yet beyond the scope of conventional acoustic noise mitigation techniques using liners, foams or ... -
Dynamic Characterization of Inertant Meta-Structures
Madhamshetty, Karthik (2018-12-01)In establishing the traditional analogies between mechanical and electrical networks, lack of preservation of topology while transitioning from a mechanical to its equivalent electrical network was rectified by so-called ... -
Exploring mechanical assonance for impact energy harvesting using acoustic metamaterials
Afework, Milkyas (2020-12)Acoustic metamaterials are engineered to possess unique dynamic properties that are not commonly found in nature. It has been demonstrated that customizing the characteristics of their local features can help optimize their ... -
Low-frequency Acoustic Noise Mitigation Characteristics of Metamaterials-inspired Vibro-impact Structures
Rekhy, Anuj (2016-12-01)Acoustic absorbers like foams, fiberglass or liners have been used commonly in structures for infrastructural, industrial, automotive and aerospace applications to mitigate noise. However, these conventional materials have ... -
Mechanical properties of a new high specific strength honeycomb from amorphous metal
Jayakumar, Balaji (2015-05)Using metallic glasses as base materials, Amorphous Metal Honeycombs (AMHs) with a teardrop cellular geometry were manufactured. A new analytical model was proposed to predict the relative density and axial compressive ... -
Nonlinear and Inertant Acoustic Metamaterials and Their Device Implications
Kulkarni, Prateek Purushottam (2016-12-01)Acoustic Metamaterials (AM) are a class of artificial structural materials that derive their unique dynamic properties, not just from material constituents but more so from engineered local configurations. Tailoring these ...
