Description of Research:
The Linear and Nonlinear Dynamics and Vibrations Laboratory (LNDVL) at the University of Illinois is co-directed by Prof. Alexander Vakakis of the Mechanical Science and Engineering Department and Profs. Lawrence Bergman and Michael McFarland of the Aerospace Engineering Department. Current research thrusts include the implementation of passive nonlinear targeted energy transfer for aeroelastic instability (flutter) suppression, vortex-induced vibration suppression, seismic mitigation, blast protection, and vibration/shock isolation of mechanical and structural components; dynamics of non-smooth dynamical systems, with emphasis on vibro-impacting systems, systems with friction, and soft materials; nonlinear system identification and reduced order modeling; structural health monitoring and damage detection; essentially nonlinear structural acoustics of granular media; strongly nonlinear micro- and nano-resonators; nonlinear vibration energy harvesting; and theoretical studies of dynamical systems and bifurcations in higher dimensional settings. Over the past twenty years, the group has involved undergraduate and graduate students, post-doctoral researchers, and international visitors. Financial support for student participation and equipment purchases has come from AFOSR, AFRL, ONR, ARO, NSF, Sandia National Laboratories, NASA and DARPA.
