Effect of Structural Parameters on the Nonlinear Vibration of L-Shaped Beams Ekici, Yigitcan; Ciğeroğlu, Ender; Yazıcıoğlu, Yiğit (2024-01-01) In this chapter, nonlinear vibration analysis of L-shaped beams is performed for different structural parameters, and the effects of these parameters are observed. The L-shaped beam is composed of two beams joined end to e...
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...
A weak-form spectral Chebyshev technique for nonlinear vibrations of rotating functionally graded beams Lotfan, Saeed; Dedekoy, Demir; Bediz, Bekir; Ciğeroğlu, Ender (2023-02-01) This study presents the spectral Chebyshev technique (SCT) for nonlinear vibrations of rotating beams based on a weak formulation. In addition to providing a fast-converging and precise solution for linear vibrations of st...
An Assessment on the Efficiency of Different Reduction Techniques Based on Substructuring for Bladed Disk Systems with Shrouds Naghizadeh, Ehsan; Ciğeroğlu, Ender (2023-01-01) Vibration analysis of shrouded bladed disk systems often becomes expensive due to friction nonlinearities and randomness stemming from mistuning phenomena. This implies a great demand for a highly efficient model order red...
Determination of Nonlinear Joint Forces and Nonlinear Identification of Jointed Connections Using FRFs Soleimani, Hossein; Ciğeroğlu, Ender; Özgüven, Hasan Nevzat (2023-01-01) The Author(s), under exclusive license to Springer Nature Switzerland AG.Identification and modeling of joint dynamics is an important issue in the dynamic modeling of structures with joints. Moreover, structures connected...
Nonlinear Vibration Analysis of Uniform and Functionally Graded Beams with Spectral Chebyshev Technique and Harmonic Balance Method Dedekoy, Demir; Ciğeroğlu, Ender; Bediz, Bekir (2023-01-01) In this paper, nonlinear forced vibrations of uniform and functionally graded Euler-Bernoulli beams with large deformation are studied. Spectral and temporal boundary value problems of beam vibrations do not always have cl...
Determination of Flutter Speed of 2D Nonlinear Wing by Using Describing Function Method and State-Space Formulation Kösterit, Güneş; Ciğeroğlu, Ender (2023-01-01) Flutter is a phenomenon that occurs in wings or platelike structures as a result of aerodynamical forces when a certain flow speed, i.e., flutter speed, is reached. Flutter results in severe vibrations which eventually lea...
A receptance based method for the calculation of nonlinear normal modes of large ordered structures with distributed localized nonlinearities Samandari, Hamed; Ciğeroğlu, Ender (2022-12-01) In recent years, the concept of nonlinear normal modes (NNMs) has gained interest for interpreting a broad range of nonlinear dynamic phenomena. Present study introduces a simple and efficient computational framework to co...
EFFECT OF NUMBER OF CONTACT POINTS ON THE FRETTING WEAR ESTIMATION OF A FRICTIONALLY DAMPED BLADE PLATFORM Cardak, Aykut; Ciğeroğlu, Ender (2022-11-03)
