This multidisciplinary project is an international collaboration between Georgia Tech, Georgia State University and Heriot-Watt University in the area of applied mathematics, nonlinear dynamics and energy harvesting with soft electroactive polymers. The project will address gaps and opportunities in mathematical developments and in practical applications for impact-based engineering devices and systems with non-smooth dynamics, critical for understanding the harvesting of vibrational energy. The main research objective is to develop a universal suite of mathematical methodologies for the analysis and optimized performance of deterministic and stochastic non-smooth engineering systems. These approaches are pursued with a focus on practical engineering models of vibro-impacting energy harvesting systems and nonlinear dynamic dampers, within the broad area of targeted energy transfer. Integrating novel nonlinear, stochastic, and computational approaches with experimental and real-world data both for energy harvesting and for devices that mitigate vibration will pave new pathways for analysis-based design and model validation.

13-14 June, 2022 – Progress and Planning for 2022
This meeting will bring together researchers working on the various projects within this NSF-EPSRC Collaborative Research Grant. Reports will cover topics including the development of new computational methods for stochastic systems, innovations for different types of impact models, new insights on parametric effects in sequences of smooth and non-smooth bifurcations, novel approaches for studying the global stability of non-smooth dynamical systems, and advances in the general area of targeted energy transfer. Planning activities will focus on the next steps for advanced stochastic models of vibro-impact energy harvesting, including integration of these approaches with experimental data and further dissemination of the results.
