Residual Stresses in Butt and Socket Welded Joints
A finite element scheme for simulation of welding residual stresses is presented in this paper. Detailed thermal and residual stress analyses for butt-welded and socket-welded pipes are performed using ANSYS and ABAQUS. The calculated distribution of axial stress and hoop stress at welded joint are validated against experimental results. Furthermore, residual stress relaxation under high amplit...
متن کاملThe Influence of Ultrasonic Impact Treatment on Fatigue Behaviour of Welded Joints in High-strength Steel
The unabated growth of the steel industry and progressively increasing operating loads on metal structures generate a need for a search for optimum engineering solutions to improve the loadcarrying capacity and reduce metal consumption. One way of resolving this problem is to utilise high-strength steels. It is common knowledge however that the improvement of the steel strength is accompanied b...
متن کاملNumerical Analysis of explosion effects on the redistribution of residual stresses in the underwater welded pipe
Structural health monitoring of cracked structures is one of beloved subject of researchers recently. Consider of crack behavior in the water and energy pipeline is important because of environmental problems. In this paper consider of crack parameters in the underwater pipe subjected to mechanical transient load is investigated. For this purpose, three- dimensional parametric model of cracked ...
متن کاملCrystallographic Texture of Induction-welded and Heat-treated Pipeline Steel
The Charpy energy of the sample after heat–treatment was significantly higher than the as–welded sample when the V–notches were located 1 or 3 mm away from FL. However, when the V–notch was located on FL, the improvement in toughness from the heat treatment was not so obvious with no enhancement noted for the test temperature of −40 ◦C. Under this condition, the facets of the fracture surface a...
متن کاملInfluence of Residual Stresses Induced by Cold Curving on the Resistance of I-section Steel Members
Cold curving is today the cheapest and more common way to produce curved steel members by bending or curving of straight members. This is a repetitive process during which the straight member passes several times through a machine with bending rolls imposing progressively the desire curvature (see for example the curving machine of figure 1). The non-reversible deformations introduced by the pr...
