About This Event

Vibrations are one of the most prolific dynamic phenomena in the universe. Vibrations can cause accelerated fatigue in mechanical components, and so engineers often are tasked with controlling them. However, vibrations also result in many complex and fascinating capabilities, such as music and chaos. Simply stated, music is orderly vibrations, while chaos is seemingly unpredictable. In this talk, music will be discussed in the context of nonlinear dynamics and musical instrument design. Chaos, which is often considered as the antithesis of music and order, will be discussed in the context of chaotic communications. Finally, several energy localization phenomena will be explored. Intrinsic localized modes and acoustic lenses could enable future technologies, including new computing techniques, energy harvesting, and passive vibration isolation.

Edmon Perkins is an assistant professor in the Mechanical Engineering Department at Auburn University. He received a PhD in Mechanical Engineering from the University of Maryland, as well as a BS and MS in Mathematics from the University of Oklahoma. His research interests include nonlinear/stochastic systems, 3D printed vibrations, acoustic metamaterials, and nonlinear control. Currently, he advises 4 PhD students and 11 undergraduates. Additionally, he was recently awarded a Young Investigator Award through the Office of Naval Research.
