Öğe Investigation of turning in different cutting parameters of Al 6061 with finite elements method(Fırat Üniversitesi, 2017-10) Çelik, Yahya Hışman; Özek, Cebeli; Türkan, CihatIn this study, the effects of cutting parameters on cutting force, temperature and stress were investigated in the turning of 6061 aluminum alloy by using DEFORM-3D package program based on finite element method. Constant depth of cut (1 mm), three different cutting speeds (40, 60 and 80 m/min), and three different feed rates (0.05, 0.1 and 0.15 mm/rev) were used in research simulations. From the made analyses, the lowest cutting force was obtained as 150 N at 80 m/min cutting speed and 0.05 mm/rev feed rate, the highest cutting force was obtained as 368 N at 40 m/min cutting speed and 0.15 mm/rev feed rate. While the lowest temperature was obtained as 230 °C at 40 m/min cutting speed and 0.05 mm/rev feed rate, the highest temperature was obtained as 354 °C at 80 m/min cutting speed and 0.05 mm/rev feed rate. In addition, the lowest stress was 997 MPa at 80 m/min cutting speed and 0.05 mm/rev feed rate, the maximum stress was 1090 MPa at 40 m/min cutting speed and 0.15 mm/rev feed rate. It has been observed that the cutting force and the stress value show a similar tendency depending on the cutting parametersÖğe The investigation of the tensile behaviors of single L-joint type bonded with adhesive and rivet(Wiley-Blackwell, 2018-08) Adin, Hamit; Kurtkan, Ümitn this study, tensile behaviour of single “L” type joints was investigated experimentally and numerically. Aluminium pieces with 2 mm, 3 mm and 4 mm thicknesses were used as joint materials. Overlap lengths were chosen as 10 mm, 15 mm and 20 mm. Joints were executed with two different rivets as steel and aluminium and 3 M 2216 epoxy based adhesive. Experiments were carried out by means of Shimadzu universal testing machine with 5 kN load cell. While the numerical study was carried out, using ANSYS Workbench, finite element analysis program, models were formed with the same properties as experimental works. Results showed that the samples with 20 mm overlap length had the highest strength of all models. Models with steel rivet had higher strength than models with aluminium rivets for all overlap lengths.Öğe The investigation of effect of adherend thickness on scarf lap joints(Wiley-Blackwell, 2013-10) Adin, HamitIn this paper, the mechanical behavior of the Scarf Lap Joints (SLJs) bonded with adhesive under a tensile load was analyzed. The effects of adherend thickness at the interface stress-strain distributions of SLJs were examined. The stress-strain analyses were performed by Finite Element Method (3D-FEM). The 3D-FEM code was employed with Ansys (Ver.12.0.1). Experimental results were compared with the 3D-FEM results and were found quite reasonable. It was concluded that both experimental and 3D-FEM failure loads were increased with increased adherend thickness. The results indicated that the maximum failure loads were determined at t=8 mm in all joints. The analysis of the SLJs under tensile load showed that the stress and strain concentrations occurred around the edges of the joints.
