International Journal of Heat and Mass Transfer. Recent developments in structural active control of cable-stayed bridges are focused on the adaptability to dynamic effects produced by earthquakes or extreme winds (El Ouni et al., 2012; Pakos and Wójcicki, 2014; Domaneschi et al., 2015a,b). governing equations was achieved using a finite element scheme based on the Galerkin method of weighted residuals. Since the flange plate is not a visual material, just one material type, the DX51D + AZ, was considered. In this case, the maximum force was recorded at the displacement of 0.5 mm during the experiments, while it was calculated at the displacement of 2.2 mm during the numerical studies. ... (1) to (3) can be stated as (see e.g. The punch and the die were scanned by a 3D scanner. Simple models present an effective use in some cases of engineering applications. OpenFOAM is the leading leading free, open source software for computational fluid dynamics (CFD) [].Featuring dedicated solvers and support for many types of flow regimes such as incompressible and compressible, turbulent, non-isothermal, and multiphase flows, OpenFOAM is a very versatile flow solver package. In the study of [26], different damaged joints are obtained by applying different damaging forces to investigate the neck thickness with a custom-built rivet and two flat dies. ME 492 Projects Fall 2019 Design of a Height Adjustable Washbasin Design of a Hydro Abrasion Test Machine Finite Element Analysis of Shape Memory Alloy Based Bending Actuator Physical Activity Recognition Using Smartphone Sensors Numerical Modelling of Non-Newtonian Fluid Flow Mechanical Analysis of Recurved, Composite Bow Design of A Linear-To-Rotary Motion Converter for During the rotation, the change of the forces for both six-clinched joints, A, B, C, D, E and F, and three-clinched joints, A, B and C (Fig. … More complex models are closer to reality and useful to engineering and research purposes. As a result, active control systems compensating quasi-static loading patterns can certainly help engineers optimise the design of these emblematic structures. Then, the regions that affect the clinching were modeled by the reverse engineering method utilizing points cloud data. and boundary condition 32 . Control of the material flow to maximize the interlock due to blank holder parameters was reported [4]. June, 1980. System Requirements: OOF2 will run on any computer running a variant of the Unix operating system, including Linux and Macintosh OS X, as long as the prerequisites listed below are available. The specific construction studied in this paper is the structural floor of a rail vehicle. The clinching process was applied to the plates shown in Fig. © 2008-2020 ResearchGate GmbH. It was figured out that the influence of stress ratio is more significant than the joint configurations (transverse and longitudinal) since it changes the failure mode in fatigue tests [2]. For this purpose, numerical and experimental tests are performed. Paris’ law, within the framework of Linear Elastic Fracture Mechanics, is used to correlate the SIF with crack size and, further, to determine \(N_p\). In the present work, natural convection mixed-mode solar drying experiments were carried out with potato cylinders of varying diameters (8, 10 and 13 mm) with … Bevill G(1), Eswaran SK, Farahmand F, Keaveny TM. In the 3rd region, the force reduces steeply and the separation is completed substantially. Metallofiz Noveishie Tekhnol 37(6):839–852, Department of Mechanical Engineering, Yildiz Technical University, 34349, Besiktas, Istanbul, Turkey, Arçelik A.S., Cerkezkoy, Tekirdag, Turkey, You can also search for this author in The sheet metal that was used at the die side for all tests is DX51D + AZ150 with a thickness of 1.5 mm. 6. This fact is illustrated in Figure 11b as well; (3) While such modifications of the time integration algorithm can be easily implemented, we instead search for remedies at the element formulation level. Thin-Walled Struct 52:42–52, Su Z, Lin P, Lai W, Pan J (2015) Fatigue analyses of self-piercing rivets and clinch joints in lap-shear specimens of aluminum sheets. Most FEA coding is still done in FORTRAN. Mechanical clinching is a fast process that provides the joining of two or more metal sheets without using additional material. To mount the test specimen to the testing machine properly it is needed to provide a longer distance between the ends of the specimen and the holder parts of the machine. The finite element method (FEM) is the dominant tool for numerical analysis in engineering, yet many engineers apply it without fully understanding all the principles. 7). Objective: To validate the fatigue lifetime of a reduced-diameter dental implant system predicted by three-dimensional finite element analysis (FEA) by testing physical implant specimens using an accelerated lifetime testing (ALT) strategy with the apparatus specified by ISO 14801. George E. Blandford. The minimum and maximum magnitudes of the shear forces with their standard deviations are presented for each material pair. ... (Third Edition) should be quite accurate since it uses a "fudge factor" for each mode to normalize the results to test data. It is observed that the separation occurs without any tearing and deformation occurs as the expansion of punch press surface for test samples of AISI 430 and H340LAD + AZ150 materials, whereas a deformation is observed around the connection for DX52D + Z275 material. To test the performance of the Small Solar Oven a 5000cm3 ... different types of solar dryer (direct, indirect and mixed-mode types) in developing countries. The tensile–shear properties of a joint by means of the force–displacement curves obtained from some experimental studies were obtained for some similar and different metal sheets were presented [17]. Mater Des 87:606–618, Chen C, Zhao S, Cui M, Han X, Fan S (2016) Mechanical properties of the two-steps clinched joint with a clinch-rivet. Tools for forming the clinching joint; a geometrical model, b basic model. It is concluded that the clinched joint formed by AISI 430 tumble endplate has the highest strength.
