The present study describes the usage of the AE technique for detecting different types of damage in corrosion process with characterization of corresponding AE sources in pre-stressed concrete cylinder pipes. Firstly, several small-scale tests were implemented to specify the characteristics of AE sources including water absorption of concrete, hydrogen bubbles bursting and concrete cracks, as well as determining the appropriate sensors positions. Later on, a full-scale pre-stressed pipe was subjected to corrosion under both constant and variable pressure; aiming to detect and classify the mixed type of damage sources. The results indicated that using AE technique, all sorts of damage sources can be classified at any stage of pipe life-cycle.

Determination of current transport characteristics in Au-Cu/CuO/n-Si Schottky diodes Surucu, O. Bayrakli; Güllü, Hasan Hüseyin; Terlemezoglu, M.; Yildiz, D. E.; Parlak, M. (Elsevier BV, 2019-10-01) In this study, the material properties of CuO thin films fabricated by sputtering technique and electrical properties of CuO/n-Si structure were reported. Temperature-dependent current-voltage (I-V) measurement was carried out to determine the detail electrical characteristics of this structure. The anomaly in thermionic emission (TE) model related to barrier height inhomogeneity at the interface was obtained from the forward bias I-V analysis. The current transport mechanism at the junction was determined ...
Computation of Thermal Fracture Parameters for Inclined Cracks in Functionally Graded Materials Using Jk-Integral Dağ, Serkan (Informa UK Limited, 2009-01-01) This article describes the formulation and implementation of the Jk-integral for the analysis of inclined cracks located in functionally graded materials (FGMs) that are subjected to thermal stresses. The generalized definition of the Jk-integral over a vanishingly small curve at the tip of an inclined crack is converted to a domain independent form that consists of area and line integrals defined over finite domains. A numerical procedure based on the finite element method is then developed, which allows t...
Investigation of structural, electronic, magnetic and lattice dynamical properties for XCoBi (X: Ti, Zr, Hf) Half-Heusler compounds Surucu, Gokhan; IŞIK, MEHMET; CANDAN, ABDULLAH; Wang, Xiaotian; Güllü, Hasan Hüseyin (Elsevier BV, 2020-06-15) Structural, electronic, magnetic, mechanical and lattice dynamical properties of XCoBi (X: Ti, Zr, Hf) Half-Heusler compounds have been investigated according to density functional theory and generalized gradient approximation. Among alpha, beta and gamma structural phases, gamma-phase structure has been found as the most stability characteristics depending on the calculated formation enthalpies, energy-volume dependencies and Cauchy pressures. Energy-volume plots of possible magnetic orders of gamma-phase ...
Investigation of band gap energy versus temperature for SnS 2 thin films grown by RF-magnetron sputtering Isik, M.; Gullu, H. H.; Terlemezoglu, M.; Surucu, O. Bayrakli; Parlak, Mehmet; Hasanlı, Nızamı (Elsevier BV, 2020-08-01) SnS2 thin films grown by magnetron sputtering technique were characterized by structurally and optically in the present work. Crystalline parameters, atomic compositions, and surface characteristics of SnS2 thin films were presented according to results of applied structural techniques. Optical studies of SnS2 thin films were accomplished by Raman spectroscopy and transmission methods. Raman spectrum exhibited two modes around 198 and 320 cm−1. Transmittance data obtained for various temperatures between 10...
A new wireless asynchronous data communications module for industrial applications EGE, Yavuz; Sensoy, Mehmet Gokhan; Kalender, Osman; Nazlibilek, Sedat; Citak, Hakan (Elsevier BV, 2013-10-01) All the sensors such as temperature, humidity, and pressure used in industry provide analog outputs as inputs for their control units. Wireless transmission of the data has advantages on wired transmission such as USB port, parallel port and serial port and therefore has great importance for industrial applications. In this work, a new wireless asynchronous data communications module has been developed to send the earth magnetic field data around a ferromagnetic material detected by a KMZ51 AMR sensor. The ...
