Finite element analysis of shearing processes

Shearing of sheet metal is extensively used in manufacturing industry. It is a highly non-linear process and involves complex mechanisms such as crack initiation and propagation, and deliberate fracture of the material for obtaining the desired geometry. Finite element method can be used for the design of shearing process. However, most of the general purpose commercial finite element analysis programs do not provide ready-to-use facilities to simulate shearing. In this paper, finite element simulation of shearing process by using the element elimination method is presented. A subroutine has been developed for this purpose and successfully integrated to a commercially available finite element program. As a case study, the finite element analysis results are given for blanking which is one of the most commonly used shearing process in industry. © 2006 Civil-Comp Press.

Springback analysis in air bending process through experiment based artificial neural networks
Senol, Ozgu; Esat, Volkan; Darendeliler, Haluk (2014-10-24)
Sheet metal bending is one of the most frequently used sheet metal forming processes in manufacturing industry. This study investigates bending parameters and springback phenomenon of a stainless-steel sheet in air bending process. In most of the applications, springback is determined either by trial and error procedures or by using numerical methods. Artificial Neural Network (ANN) approach has proved to be a helpful tool for the engineers. ANN is used in this study to predict the springback amounts of sta...
Computer aided modeling of deep-drawing
Piskin, Mehmet Ali; Kaftanoglu, Bilgin (2007-04-04)
Deep-drawing operations are performed widely in industrial applications. It is very important for efficiency to achieve parts with no defects. in this work, a finite element method is developed to simulate deep-drawing operation including wrinkling. A four nodded five degree of freedom shell element is formulated. Isotropic elasto-plastic material model with Von Mises yield criterion is used. By using this shell element, the developed code can predict the bending behavior of workpiece besides membrane behav...
Finite element analysis of springback in bending of aluminium sheets
Esat, V; Darendeliler, Haluk; Gokler, MI (2002-04-01)
Bending is one of the processes frequently applied during manufacture of aluminium components. The bending operation involves springback, which is defined as elastic recovery of the part during unloading. In manufacturing industry, it is still a practical problem to predict the final geometry of the part after springback and to design appropriate tooling in order to compensate for springback. In this paper, commercially available finite-element analysis (FEA) software is used to analyse bending and springba...
Finite Element Modelling of TBC Failure Mechanisms by Using XFEM and CZM
Bostanci, Safa Mesut; Gürses, Ercan; Çöker, Demirkan (Elsevier BV; 2019-01-01)
Thermal Barrier Coatings have been widely used in modern turbine engines to protect the nickel based metal substrate from the high temperature service conditions, 1600-1800 K. In this study, failure mechanisms of typical Air Plasma Sprayed Thermal Barrier Coatings (TBC) used in after-burner structures composed of three major layers: Inconel 718 substrate, NiCrAlY based metallic bond coat (BC) and Yttria Stabilized Zirconia (YSZ) based ceramic top coat (TC) are investigated. Investigation of the cracking mec...
Investigating the effect of deformation and annealing texture on magnetic anisotropy in low-C steel sheets by magnetic Barkhausen noise method
Akçaoğlu, Fehmi Ümit; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2013)
Deformation and annealing texture in the cold rolled low carbon steels is important for sheet metal forming operations and service performance. The aim of this study is to non-destructively investigate the effect of texture on magnetic anisotropy. Various samples having different textures and residual stress states, due to different % reduction in thickness, annealing and stress relieving treatment, were prepared. Texture maps were obtained by Magnetic Barkhausen noise measurements performed with 100 steps ...
