Fatigue and static behavior of curved composite laminates
Taşdemir, Burcu; Çöker, Demirkan; Department of Aerospace Engineering (2018)
By virtue of the fact that curved composite laminates which are utilized as load carrying subcomponents in aircraft and wind turbine structures are subjected to cyclic loading during their operating time, it is crucial to understand fatigue failure mechanisms at least as much as static failure mechanisms. With the intention of understanding fatigue failure mechanisms and thus improving fatigue life of structures, these curved laminates are investigated experimentally under static and fatigue loadings. The f...
Fatigue in jointless bridge H-piles under axial load and thermal movements
Karalar, Memduh; Dicleli, Murat (Elsevier BV, 2018-08-01)
The seasonal and short-term temperature variations produce cyclic horizontal displacements in the continuous superstructure of jointless bridges and hence in the abutment piles. Thorough study of the available field measurement data for jointless bridges showed that the thermal-induced cyclic flexural strains in steel H-piles (SHPs) at the abutments are composed of large, primary small and secondary small flexural strain cycles. While the SHPs at the abutments of jointless bridges laterally deform and exper...
Fatigue performance of engineered cementitious composites

The maintenance and rehabilitation of a pavement during its service life is as much important as the construction works of this pavement. In this scope, applying the correct and efficient repair method is highly critical for economic and technical reasons. Depending on the damage level of the pavement, there are many different methods that can be used to repair the pavement. The use of an overlay is one of the most common methods, where a new layer can be applied directly over or replace the top part of an ...
Fatigue and fracture analysis of helicopter fuselage structures
Özcan, Rıza; Dağ, Serkan; Department of Mechanical Engineering (2013)
In this study a methodology is developed for the fatigue and fracture analysis of helicopter fuselage structures, which are considered as the stiffened panels. The damage tolerance behavior of the stiffened panels multiaxially loaded is investigated by implementing virtual crack closure technique (VCCT). Validation of VCCT is done through comparison between numerical analysis and the studies from literature, which consists of stiffened panels uniaxially loaded and the panel with an inclined crack. A program...
Fatigue behavior of Ti-6Al-4V foams processed by magnesium space holder technique
Asik, E. Erkan; Bor, Sakir (2015-01-05)
Porous Ti-6Al-4V alloys are widely used in the biomedical applications for hard tissue implantation due to their elastic moduli being close to that of bone. In this study, porous Ti-6Al-4V alloys were produced with a powder metallurgical process, space holder technique, where magnesium powders were utilized to generate porosity in the range of 51-65 vol%. The production of porous Ti-6Al-4V alloys was composed of three steps. Firstly, spherical Ti-6Al-4V powders with an average size of 55 mu m were mixed wit...
