Investigation of Surface Residual Stresses on the Deep-Drawn Steel Sheets



Investigation of mechanical property changes after MIG welding of (7XXX) series aluminum alloys
Okay, Sena; Ögel, Bilgehan; Batıgün, Caner; Department of Metallurgical and Materials Engineering (2016)
There is an increasing demand for aluminum alloys not only in aerospace industry but also in automotive industry due to its low density. Welding is the most effective and commonly used joining technique in those industries, therefore, aluminum welding plays an important role. 7039 aluminum alloy, is a high strength alloy and it is suitable for armor applications. Like other aluminum alloys, after MIG welding, remarkable decrease in strength is observed and therefore applications are restricted. The aim of t...
Investigation of productivity of heavy oil carbonate reservoirs and oil shales using electrical heating methods
Hasçakır, Berna; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2008)
The recovery characteristics of Bolu-Himmetoglu, Bolu-Hatıldag, Kütahya- Seyitömer, and Nigde-Ulukısla oil shale samples and Batı Raman, Çamurlu, and Garzan crude oil samples were tested experimentally using retort and microwave heating techniques. Many parameters like heating time, porosity, water saturation were studied. To enhance the efficiency of the processes three different iron powders (i.e.; Fe, Fe2O3, and FeCl3) were added to the samples and the doses of the iron powders were optimized. While crud...
Investigation of the effect of shearing rate on residual strength of high plastic clay
Akis, Ebru; Mekael, Ahmad; Yılmaz, Mustafa Tolga (Springer Science and Business Media LLC, 2020-01-09)
The residual shear strength on failure plane is a crucial parameter to be estimated for analysis of an active landslide. This strength must be determined precisely to build a reliable theoretical model for calculations. The multi-reversal direct-shear test is a practical method to determine this shear strength in laboratory due to wider availability of apparatus. The shearing rate is among the factors that significantly affect the precision of test results for clay specimens. However, limits for this rate a...
