Welcome!

Our research explores complex nonlinear phenomena observed in structural dynamics. We focus on developing validated models, computationally efficient solution methodologies, and innovative experimental and measurement techniques to support and refine theoretical findings.

These fundamental studies find application in a wide range of mechanical engineering systems, from high-performance power transmission systems to micromechanical resonators used in sensing applications.

Multiple MSc, PhD, and Postdoctoral positions are available in our group. Interested candidates are encouraged to contact Dr. Ata Donmez at ata.donmez@bilkent.edu.tr.

A key research focus of our group is nonsmooth nonlinearities caused by mechanical contact. These stiff nonlinearities make system dynamics extremely sensitive to operating and structural parameters. The bouncing-ball simulator below is a toy example that highlights this sensitivity — experiment with parameter changes to observe how motion and overall system behavior respond. Such nonlinear effects have important implications for analysis, control, and design of engineering systems. See our Research and Publications pages for details.
