This paper presents the results obtained by numerical simulation regarding springback phenomenon of a U-shaped part manufactured from tailor welded stripes. The final shape of the formed part is seriously affected by springback phenomenon. This paper work is trying to prove the important role the metal sheet thickness on the springback effect. The U-shaped part has different springback values f...

In this study, the concrete-steel bond strength of concrete filled cylindrical steel tubes has been experimentally investigated. 22 short, high strength and normal concrete filled circular steel tubes were tested. Push-out test was carried out as the common method to evaluate the bond carrying capacity. Four different concrete mixes were used in preparing the specimens. The steel tubes were w...

Welded beam-to-column connections of high-rise steel structures are susceptive to fatigue damage under wind loading. However, most fatigue assessments in the field of civil engineering are mainly based on nominal stress or hot spot stress theories, which has the disadvantage of dependence on the meshing styles and massive curves selected. To address this problem, in this paper, the equivalent s...

A 14.5 GHz ECRIS has been designed and fabricated at KAERI (Korea Atomic Energy Research Institute) to produce multi-charged ion beam (especially for C ion beam) for medical application. The magnet system has cupper conductor solenoid coils and a permanent magnet hexapole. A welded tube with aluminium and stainless steel is used for an ECR plasma chamber to improve the production of secondary e...

Al-Si is the most popular coating used to prevent oxidation on surfaces of hot-stamped steel sheets during heating process. However, like other coatings, it affects strength spot welds in joining parts. In this study, effects tensile resistance spot-welded joints are discussed. Two types 1.8 mm steel, uncoated and coated forms, were spot-welded, shear behavior welded was studied both static dyn...

The weld quality of Tunston inert gas welded joint has been investigated to identify the most economical weld parameters that will bring about optimum properties. Artificial neural network, has been used in the prediction and optimization of the Tunston inert gas weld of mild steel pipes. Neural network model was generated using the Levenberg-Marquardt algorithm with feed ward back propagation ...

After the huge earthquake many steel structures were constructed using frame welded joints of construction and base. Steel are considered resistance however, frame-welded fillet column bases. These weld could result to have low capacity absorb energy during earthquakes. Therefore, application structural health monitoring maintenance infrastructures is extensively expected for new technology. Ho...

in this paper, dissimilar resistance spot welding of aisi 1075 eutectoid steel to aisi 201 stainless steel is investigated experimentally. for this purpose, the experiments are designed using response surface methodology and based on four-factor, five-level central composite design. the effects of process parameters such as welding current, welding time, cooling time and electrode force are inv...
