Investigation of low cycle fatigue in integral bridge steel h-piles under seismic displacement reversals

13th International Conference on Steel, Space and Composite Structures (2018)


Gozluklu, B.; Uyar, I; Çöker, Demirkan (2014-07-25)
In wind energy and aerospace industries, new advances in composite manufacturing technology enable to produce primary load carrying elements as composite materials in wide variety of shapes large such as an L-shape. However, due to the geometry, Interlaminar Normal Stresses (ILNS) are induced once a moderately thick laminate takes highly curved shape. In the curved part of the L-shaped structure, the development of ILNS promotes mode-I type of delamination propagation which is the weakest fracture mode. Thi...
Investigation of tensile plastic instability and necking for AL2024T3 aluminum and S235JR steel alloys
İli, Volkan; Darendeliler, Haluk; Department of Mechanical Engineering (2019)
Tensile plastic instability phenomenon is defined as the mode of deformation so that large amounts of deformation is localized in a certain region of a component during product life or testing procedure. Several studies have been published to assess the methods proposed to predict tensile plastic instability and necking behavior of materials. Although research has been done by using various specimens, comparative results on different specimen materials and geometries as well as different test methods have n...
Investigation of warpage behavior of single crystal silicon on a silicon Adhesive ceramic integrated structure at cryogenic temperatures
Baloğlu, Can; Okutucu Özyurt, Hanife Tuba; Dursunkaya, Zafer (2016-03-17)
Understanding thermal stress and warpage behavior of heterogeneous component assemblies is vital in infrared sensor applications of silicon semiconductor material. The silicon semiconductor warpage behavior of the integrated structure composed of silicon material itself, an adhesive layer and a ceramic layer is analyzed by both FEM and experimental studies. The studies are performed between room temperature and 80 K. Thickness of each layer has an effect on the warpage. The silicon warpage of the initial ba...
Investigation of interaction between pressure relief valve and turbines during a transient flow in hydropower plant
Çetintaş, Mehmet Ali; Bozkuş, Zafer; Çelebioğlu, Kutay; Department of Civil Engineering (2022-2)
The main goal of the present study is to investigate the effect of pressure relief valve (PRV) on the hydraulic transients generated by multiple turbine operations. To achieve this goal, a numerical model of KEPEZ-I Hydropower plant is constructed in the Bentley HAMMER software, which employs the Method of Characteristics (MoC) for computations. The MoC has been proven worldwide as a versatile and accurate tool for solving non-linear, hyperbolic, partial differential equations in space-time domain for hydra...
Investigation of SiCp reinforced aluminium matrix composites by shear and longitudinal ultrasonic waves
Gür, Cemil Hakan (2001-11-01)
SiC particulate reinforced aluminium matrix composites are attractive materials for automotive and aerospace applications because of their outstanding stiffness and strength as compared to the aluminium alloys, in addition to the low cost of particulate reinforcement. The aim of this study is to establish correlations between ultrasonic wave velocities and SiC content, microstructure and mechanical properties of SiC reinforced Al composites, Specimens were fabricated for various volume fraction and size com...
