Investigating the effects of hardening of aluminium alloys on equal-channel angular pressing-A finite-element study
Karpuz, P.; Simsir, C.; Gür, Cemil Hakan (Elsevier BV, 2009-03-15)
Equal-channel angular pressing (ECAP) is a promising severe plastic deformation method for production of ultrafine-grained bulk metals and alloys with considerably improved mechanical properties. In this study, numerical experiments were carried out to investigate the effect of strain hardening of aluminum alloys on the process performance of ECAP via finite element modeling. In the constitutive model, isothermal-plane strain, frictionless condition was assumed. The numerical results showed that strain hard...
Investigating suitability of software process and metrics for statistical process control
Tarhan, Ayca; Demirörs, Onur (2006-01-01)
The application of statistical process control (SPC) techniques for software is rare due to such requirements as high maturity, rational sampling, and effective metric selection. Existing studies report results from their own implementations and provide suggestions for success. In this paper, we explain an approach used for assessing the suitability of software process and metrics for starting SPC implementation via control charts. The approach includes guidance to identify rational samples of a process as ...
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 ...
Investigating the mechanical properties of single walled carbon nanotube reinforced epoxy composite through finite element modelling
Zuberi, Muhammad Jibran Shahzad; Esat, Volkan (2015-03-15)
Varying experimental results on the mechanical properties of carbon nanotube reinforced polymer composites (CNTRPs) have been reported due to the complexities associated with the characterization of material properties in nano-scale. Insight into the issues associated with CNTRPs may be brought through computational techniques time- and cost-effectively. In this study, finite element models are generated in which single walled carbon nanotube models are embedded into the epoxy resin. For modelling interface...
