Bandwidth of Linear Classically Damped Systems with Application to Experimental Model Aircraft
Benjamin J. Chang, Keegan J. Moore, Lawrence A. Bergman +2
Bandwidth is a widely known concept and tool used in structural dynamics to measure an oscillator's capacity to dissipate energy over time, for example when used in half-power damp…

Understanding Modal Interactions in Non-classically Damped Linear Oscillators with Closely Spaced Modes
Luis M. Baldelomar Pinto, Alireza Mojahed, Sobhan Mohammadi +3
This work addresses non-classically damped coupled oscillators with closely spaced modes focusing on the physics of modal interactions. Considering the simplest representative exam…
