A Novel Approach for Local Structural Modification of Nonlinear Structures Ceren Ekinci, E.; Bülent Özer, M.; Özgüven, Hasan Nevzat (2024-01-01) Structural modification methods provide powerful tools to calculate the dynamic behavior of a modified structure from that of the original one. In general, either the modal properties or responses of the original structure...
The TRChallenge: Experimental Quantification of Nonlinear Modal Parameters and Confrontation with the Predictions Bhattu, Arati; Jamia, Nidhal; Hermann, Svenja; Müller, Florian; Scheel, Maren; Özgüven, Hasan Nevzat; Schwingshackl, Christoph; Krack, Malte (2024-01-01) In recent years, the prediction of the behavior of structures with high-level nonlinearities has been a challenging area of research. In 2021, the Tribomechadynamics Research Challenge was proposed to evaluate the current ...
Nonlinear Vibration Analysis of a Two-Blade System with Shroud-To-Shroud Contact by using Response Dependent Nonlinear Normal Modes Ahi, Tahsin; Ciğeroğlu, Ender; Özgüven, Hasan Nevzat (2024-1) Periodic forced response analysis of nonlinear real systems is a computationally demanding task. In order to reduce the computational burden, different approaches are proposed in the literature. The reduced computational e...
Experimental Sub-structuring for Linear and Nonlinear Connection Dynamics: A Tutorial - Part 2: Nonlinear Joints Özgüven, Hasan Nevzat (2024-1)
Extension and Experimental Verification of an Efficient Re-Analysis Method for Modified Non-linear Structures Ekinci, Ceren; Karaağaçlı, Taylan; Çelik, Furkan Kaan; Özer, Mehmet Bülent; Özgüven, Hasan Nevzat (2024-1) Design changes often occur during engineering applications. Although there are numerous methods to implement these changes and efficiently calculate dynamic responses of modified linear systems; modification methods applic...
Experimental Modal Analysis of Structures with High Nonlinear Damping by Using Response-Controlled Stepped-Sine Testing Karaağaçlı, Taylan; Özgüven, Hasan Nevzat (2024-01-01) In the last decade, various promising nonlinear modal identification techniques have been developed based on the nonlinear normal mode (NNM) concept. Most of these techniques rely on the phase resonance testing approach wh...
DEPREM VE MAKİNA TİTREŞİMLERİNDEN KORUNMAK İÇİN TİTREŞİM YALITIMI Özgüven, Hasan Nevzat (TMMOB Makina Mühendisleri Odası, 2023-9)
The Tribomechadynamics Research Challenge: Confronting Blind Predictions for the Linear and Nonlinear Dynamics of a Novel Jointed Structure with Measurement Results Özgüven, Hasan Nevzat; et. al. (2023-3-8) The present article summarizes the submissions to the recently announced Tribomechadynamics Research Challenge. The task was a blind prediction of the vibration behavior of a system comprising a thin plate clamped on two s...

Bypassing the Repeatability Issue in Nonlinear Experimental Modal Analysis of Jointed Structures by using the RCT-HFS Framework Özgüven, Hasan Nevzat; Gürbüz, M. Fatih; Karaağaçlı, Taylan (2023-2-13) Mechanical joints, which are indispensable for almost all mechanical systems, are often an important source of nonlinearity due to frictional, backlash and/or preload effects. Recent studies have shown that the contact pr...
