Residual stress distributions in multipass welded API 5L X70 steel plates were determined by numerical and experimental methods. SYSWELD finite element software was used for numerical simulations. Microstructure variations were also considered for calculation of residual stresses. The continuous cooling transformation diagram was obtained via JMatPro software. The results showed that residual stress distribution is sensitive to number of weld passes, and microstructure changes. The simulation results were compared with those obtained by Magnetic Barkhausen Noise measurements on the welded plates. Simulation and experimental results gave qualitatively similar tendencies for the variation of the residual stress state.

Numerical and experimental determination of the residual stress state in multipass welded API 5LX70 plates Garipova, Nuriya; Batıgün, Caner; Gür, Cemil Hakan (2014-01-01) Residual stres s distributions in multipass welded API SL X70 steel plates were determined by numerical and experimental methods. SYSWELD finite element software was used for numerical simulations. Microstructure variations were also considered for calculation of residual stresses. The continuous cooling transformation diagram was obtained via JMatPro software. The results showed that residual stress distribution is sensitive to number of weld passes, and microstructure changes. The simulation results were ...
Numerical investigation of residual stresses, distortion and microstructure evolution in multi-pass welded steel components Garipova, Nuriya; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2016) Formation of residual stresses, distortion and microstructure evolution in multi-pass welding and surfacing welding on pipeline HSLA steels were numerically investigated. A procedure for three-dimensional finite element analysis of temperature field, stress-strain state and phase changes in weldments was developed by using ESI SYSWELD & VISUAL WELD software. Numerical results were verified by comparisons with the results of various tests and measurements, such as molten pool profile calibration, microstruct...
Application of Continuum Damage Mechanics in discontinuous crack formation: Forward extrusion chevron Soyarslan, Celal; TEKKAYA, AHMET ERMAN; Akyüz, Uğurhan (2008-06-01) Materializing Continuum Damage Mechanics (CDM), numerical modeling of discrete internal cracks, namely central bursts, in direct forward extrusion process is presented. Accordingly, in a thermodynamically consistent setting, a local Lemaitre variant damage model with quasi-unilateral evolution is coupled with hyperelastic-plasticity. The formulations are constructed in the principal axes where simultaneous local integration schemes are efficiently developed. To this end, the framework is implemented as ABAQ...
Vibration characteristics of various wide flange steel beams and columns Özel, Halil Fırat; Sarıtaş, Afşin; Tasbahjı, Tayseer (null; 2015-12-11) Vibration characteristics of steel framed structures are affected by accurate modelling of the mass and stiffness matrices of beam and column members. In this regards, wide flange sections are the most popularly used steel sections, and calculation of axial, flexural and shear responses of these sections become critical. In this study, a mixed formulation frame finite element is developed from three-fields Hu-Washizu-Barr functional. Consistent mass matrix of the element is obtained such that determination ...
Investigating the Effects of Subsequent Weld Passes on Surface Residual Stresses in Steel Weldments by Magnetic Barkhausen Noise Technique Gür, Cemil Hakan; Batıgün, Caner; Çam, İbrahim (2016-03-01) Variations of surface residual stresses with subsequent weld passes were investigated in API 5L X70 steel plates by the magnetic barkhausen noise (MBN) technique. The plates were welded by applying a number of different passes under fully clamped conditions. After each weld pass, the MBN signal and hardness distributions on the front and back surfaces of the plates were measured. A specific calibration procedure and setup were used for conversion of the MBN signals into elastic stress values. The results we...
