Design of an experimental setup to determine the coefficient of static friction of the inner rings in contact with the outer rings of radial spherical plain bearings
Ozturk, Erkan; Yildizli, Kemal; Memmedov, Royal; Ulgen, Ahmet (Elsevier Sci Ltd, 2018)In this study, a new experimental setup was designed and manufactured to determine the coefficient of static friction (COFS) for polyoxymethylene (POM)/steel spherical contact surfaces in radial spherical plain bearings. ... -
The effect of nanoparticle-added solid lubricant on the formability of sheet metal
Sahin, Fevzi; Dengiz, Cengiz Gorkem; Yildizli, Kemal; Namli, Lutfu (Springer International Publishing Ag, 2019)In sheet metal forming processes, formation without fracture is related to sheet metal formability. Parameters such as tool geometry, blank holder force, and lubricant are changed in order to push the formability of material ... -
Effect of phase shape and size on the FEM analysis of indentation test of duplex stainless steel microstructures
Dengiz, Cengiz Gorkem; Yildizli, Kemal (Springer International Publishing Ag, 2020)This study presents the effect of modelling the microstructure of duplex stainless steels with different geometric shapes and sizes on the indentation test results. In this study, an indentation test is modelled on duplex ... -
Evaluation of Water Sorption-solubility and Surface Roughness of Different Bulk Fill Composite Resins
Gonulol, Nihan; Sen Tunc, Emine; Ozer, Sezin; Yildizli, Kemal (Galenos Yayincilik, 2019)Objective: This study aimed to investigate and compare the water sorption (WS), solubility (SO) and surface roughness (SR) of four bulk fill resin-based composites (RBCs), a conventional flowable RBC and a conventional ... -
Experimental and numerical study of process limits for deep drawing of dome-structured sheet metals
Dengiz, Cengiz G.; Yildizli, Kemal (Springer London Ltd, 2017)The demand for lightweight materials is increasing due to energy saving in the sheet metal forming industry. Structured sheet metals are a strong yet lightweight material. But the process limits for deep drawing of structured ... -
Investigation on the microstructure and toughness properties of austenitic and duplex stainless steels weldments under cryogenic conditions
Yildizli, Kemal (Elsevier Sci Ltd, 2015)This study presents deep-resolved metallurgy and fractography of the weldments beyond the routine examination of the welded constructions working under cryogenic conditions. Duplex-austenitic and austenitic-austenitic ... -
Measured Cutting Forces in the Turning of Prismatic Parts at Different Spindle Speeds and Side Cutting Edge Angles
Ozturk, Erkan; Yildizli, Kemal (Springer Heidelberg, 2018)This study attempted to measure three cutting force components simultaneously for prismatic parts and determine the force-time characteristics until face turning was finished. A calibrated dynamometer was used in the turning ... -
A new static calibration methodology for strain gage integrated dynamometers
Ozturk, Erkan; Yildizli, Kemal (Springer London Ltd, 2017)This study attempted to produce a new static calibration methodology for strain gage integrated dynamometers, which can measure three cutting force components simultaneously. In this framework, a dynamometer and two ... -
Sliding/rolling wear performance of plasma nitrided H11 hot working steel
Karamis, Mehmet Baki; Yildizli, Kemal; Aydin, Gamze Carkit (Elsevier Sci Ltd, 2012)H11 steel discs were tested by considering sliding/rolling friction under dry and lubricated conditions. The H11 discs were plasma nitrided at 500 degrees C and 550 degrees C for 9 h. Wear tests were conducted at different ...
