A conventional 4-Hi cold rolling mill configuration was modelled and a computer program was developed to analyze the effects of inlet thickness, width, desired exit thickness, symmetric and asymmetric jack forces, screw positions, tensions on the strip, roll geometries, and material properties on strip shape and thickness. For the analysis, the finite difference method was used as the discretization technique. The roll force was obtained by integrating the calculated roll-pressure over the are of contact, and elastic distortion of rolls due to the strip interaction was also considered, For determining inter-roll force, the compatibility equation between work and backup rolls was expressed in terms of work and backup roll axis deflection and work roll surface deformation. The second compatibility equation between work roll and strip was expressed in terms of work roll axis deflections, work roll surface deformation, and estimated strip thickness. The calculated thickness distribution was used for determining shape.

Numerical analysis of thermo-mechanical behavior in flow forming Günay, Enes; Fenercioglu, Tevfik Ozan; Yalçınkaya, Tuncay (2021-01-01) Flow forming is a metal forming process for cylindrical workpieces where high velocity deformation leads to radial thinning and axial extension. In the current study, a thermomechanical, dynamic and explicit finite element model of a flow forming process is developed on ABAQUS software. The model is validated through the comparison of reaction forces and geometry obtained from the experiments. Coolant convection effect is analyzed in conjunction with roller and mandrel conduction cooling to study the therma...
Computational analysis of hydrodynamics of shear-thinning viscoelastic fluids in a square lid-driven cavity flow YAPICI, KERİM; Uludağ, Yusuf (2013-11-01) Computational results for steady laminar flow of three different shear thinning fluids lid-driven square cavity are presented. The viscoelastic nature of the fluids is represented by linear and exponential Phan-Thien Tanner (PTT) and Giesekus constitutive models. Computations are based on finite volume technique incorporating non-uniform collocated grids. The stress terms in the constitutive equations are approximated by higher-order and bounded scheme of Convergent and Universally Bounded Interpolation Sch...
Numerical and experimental analysis for comparison of square, cylindrical and plate fin arrays in external flow İnci, Aykut Barış; Bayer, Özgür; Department of Mechanical Engineering (2018) Geometrical optimization of square, cylindrical and plate fins for heat transfer augmentation is numerically performed in the external flow. Heat transfer performance of fins with different profiles are compared with same Reynolds number. The relation between the thermal characteristic of fins and boundary conditions like free-stream velocity and heat input are investigated. Experimental studies are performed using manufacturable fins to validate numerical model. Heat transfer correlations are derived in or...
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 ...
Numerical investigation of stiffened composite panel into buckling and post buckling under combined loading Akay, Erkan; Yaman, Yavuz; Department of Aerospace Engineering (2015) This thesis presents the investigation of buckling and post buckling behaviour of stiffened thin walled laminated composite aerospace structures subjected to combined in-plane axial and shear loadings. Due to the fact that the state of stress developing especially in the post-buckling stage is quite complicated under the combined loading, the necessary computational model is usually based on Finite Element Modelling (FEM). In this study, after verifying the FEM methodology and completing the sensitivity stu...
