Mechanical fatigue is an important phenomenon when the structures are exposed to dynamic, fluctuating loadings. Especially aerospace structures are commonly exposed to random vibration loadings. In this paper, random vibration fatigue is studied both numerically and experimentally. For this purpose, a rectangular cross-section notched beam is designed in order to conduct the vibration fatigue analysis in the frequency domain by the Dirlik's damage model. Aluminum and steel notched beams are prepared in order to carry out the vibration fatigue tests to compare with the fatigue analysis results. The effect of modal damping on the vibration fatigue analysis results is particularly studied. (c) 2019 The Authors. Published by Elsevier B.V.

Vibration fatigue analysis and testing of notched beams
Demirel, Gürzap İsmail; Kayran, Altan; Department of Aerospace Engineering (2019)
Mechanical fatigue is an important phenomenon when the structures are exposed to dynamic, fluctuating loadings. Especially aerospace structures are commonly exposed to random vibration loadings. Even if the components are stable and durable for static requirements, vibration fatigue failures can occur due to the dynamic and fluctuating loadings. Moreover, if the loading frequency has a wide bandwidth as in random vibration loadings, the natural frequencies or resonance regions of the structures are disturbe...
Vibration fatigue analysis of structures under broadband excitation
Koçer, Bilge; Dağ, Serkan; Department of Mechanical Engineering (2010)
The behavior of structures is totally different when they are exposed to fluctuating loading rather than static one which is a well known phenomenon in engineering called fatigue. When the loading is not static but dynamic, the dynamics of the structure should be taken into account since there is a high possibility to excite the resonance frequencies of the structure especially if the loading frequency has a wide bandwidth. In these cases, the structure’s response to the loading will not be linear. Therefor...
Estimation of effective parameters and operational response of tuned vibration absorbers
Özden, Hasan Can; Özgen, Gökhan Osman; Department of Mechanical Engineering (2019)
In this study, swing up and stabilization of on/off type of cold gas thruster driven inverted pendulum is accomplished. First, pulse width modulator (PWM) design method is generated to obtain quasi-linear thrust output from on/off type of thruster. Than, single axis angle controller is designed. Designed angle controller and PWM scheme are tested and verified on single axis angle control test setup. Finally, an other freedom is attached to single axis test setup and rotary inverted pendulum (Furuta Pendulum...
Vibration Fatigue Analysis of a Cantilever Beam Using Different Fatigue Theories
Eldoğan, Yusuf; Ciğeroğlu, Ender (2014-02-11)
In this study, vibration fatigue analysis of a cantilever beam is performed using an in-house numerical code. Finite element model (FEM) of the cantilever beam verified by tests is used for the analysis. Several vibration fatigue theories are used to obtain fatigue life of the cantilever beam for white noise random input and the results obtained are compared with each other. Fatigue life calculations are repeated for different damping ratios and the effect of damping ratio is studied. Moreover, using strain...
Analysis of the thermoviscoplastic behavior of [0/90] SCS-6/timetal®21S composites
Çöker, Demirkan; Nicholas, Theodore (1996-01-01)
Micromechanical modeling is used to determine the stresses and strains due to both mechanical and thermal loads in [0/90] titanium matrix composites (TMCs) subjected to cooldown from the processing temperature and subsequent thermomechanical fatigue (TMF) loading conditions. The [0/90] composite is treated as a material system composed of three constituents: fiber and matrix in the [0] ply, and a [90] ply. The [0/90]s layup is modeled by a uniaxial stress rule of mixtures model for the [0] ply and adding a ...
