Research

Erturk leads the Smart Structures and Dynamical Systems Laboratory{{cite web|url=http://www.ssdsl.gatech.edu/ |title=Smart Structures & Dynamical Systems Laboratory |website=Ssdsl.gatech.edu |date= |access-date=2017-02-24}} at Georgia Tech. His publications are mostly in the areas of dynamics, vibration, and wave propagation involving smart materials and metamaterials.{{cite web|url=https://scholar.google.com/citations?user=OwypZqcAAAAJ&hl=en |title=Alper Erturk - Google Scholar Citations |website=Scholar.google.com |date= |access-date=2017-02-24}} Erturk made fundamental contributions in the field of energy harvesting from dynamical systems. His distributed-parameter piezoelectric energy harvester models{{cite journal |doi=10.1115/1.2890402 |title=A Distributed Parameter Electromechanical Model for Cantilevered Piezoelectric Energy Harvesters |journal=Journal of Vibration and Acoustics |volume=130 |issue=4 |page=041002 |year=2008 |last1=Erturk |first1=A. |last2=Inman |first2=D.

He was one of the first researchers to explore nonlinear dynamic phenomena for frequency bandwidth enhancement in energy harvesting, specifically by using a bistable Duffing oscillator with electromechanical coupling, namely the piezomagnetoelastic energy harvester.{{cite journal |doi=10.1063/1.3159815 |title=A piezomagnetoelastic structure for broadband vibration energy harvesting |journal=Applied Physics Letters |volume=94 |issue=25 |page=254102 |year=2009 |last1=Erturk |first1=A. |last2=Hoffmann |first2=J. |last3=Inman |first3=D. J. |bibcode=2009ApPhL..94y4102E |hdl=10919/47364 |hdl-access=free }} His early energy harvesting work also included the use of aeroelastic flutter to enable scalable airflow energy harvesting through piezoaeroelastic systems.{{cite journal |doi=10.1063/1.3427405 |title=On the energy harvesting potential of piezoaeroelastic systems |journal=Applied Physics Letters |volume=96 |issue=18 |page=184103 |year=2010 |last1=Erturk |first1=A. |last2=Vieira |first2=W.
