“…Comparison with published experimental plastic limit load data showed that the predictions agreed relatively well with the test data. Lee et al [158] investigated by the FEM the buckling behaviour of girth-welded circular steel tubes subjected to bending. Elastoplastic large-deformation analysis incorporating weld-induced geometric imperfection and residual stress was carried out.…”

“…Combining the experimental data with references [ 6 , 14 , 36 ], the residual stress distribution model shown in Figure 9 was proposed. Because the left and right sides of the cross-section are symmetrical, the residual stress distribution at the left and right sides is also assumed to be symmetrical, but only the residual stress distribution of the right side is shown.…”

“…Anas et al [ 12 ] carried out experiments on the welding residual stress of P91 pipe after post-weld heat treatment and the finite element method of modelling residual stresses is presented. Lee et al [ 13 , 14 ] conducted experiment and numerical simulation on welded high-strength steel thin-walled plate-to-plate joints and discussed the influence of some key welding parameters on the magnitude and distribution of residual stress. Trayana et al [ 15 ] used data from the experiment and numerical results and the literature on welding residual stress distribution of steel members in which I-beams were analyzed.…”

BS700 high-strength steel is widely used in engineering. Welding residual stress during the manufacturing process has a significant influence on the structural safety and service life of steel structures. In this study, the residual stress of a BS700 butt-welded box section axial compression member was studied by the blind-hole method, its distribution law was summarized, and a residual stress distribution model was established. By establishing a finite element model considering initial geometric imperfection and residual stress, the influence of residual stress on the stability of axial compression members was analyzed. The results illustrated that the residual tensile stress near the weld in the welded box section axial compression members was the largest: the average residual tensile stress reached 76.6% of the measured steel yield strength, the residual tensile stress at the roof and web were almost the same, and the residual tensile stress at the corner was approximately 11.6% of the measured yield strength. The residual stress had a different influence on the stability factor of the axial compression members with different width-thickness ratios, and the influence decreased with the increase in the width-thickness ratio. In addition, when the slenderness ratio of members ranged between 20 and 70, the residual stress had a significant influence on the stability of members, while outside that interval, the influence was relatively small.

“…The same calibration loading P c was re-applied and the corresponding Gird 1and Grid 3 strains ε 1 and ε 3 were recorded. To make the results more reliable, eight groups of readings were recorded to obtain coefficients "a" and "b" that are required by the ASTM standard [14] at different depths ranging from 0 to 2mm with 0.25mm steps. …”

Welded joint is most commonly used for building structures and machine components. Welding process involves heating followed by uneven cooling causing residual stress field. In conjunction with stresses due to external loads, in-service behaviour is affected due to residual stress in welded components. It induces defects, also alters crack initiation life, fatigue behaviour, breaking strength, corrosion resistance and increases the susceptibility of structure to failure by fracture. The residual stress is function of cooling rate and the size of weld. The role of residual stress associated with welding is therefore very important while designing mechanical parts. Conventional methods like heat treatment and shot-peening techniques becomes difficult to be applied for reduction of residual stress in general purpose applications. The work presented in this paper describes the measurement of residual stress using stress relieving method, based on hole-drilling technique. Subsequently, residual stresses are relived and measured using strain rosette near the weld zone. These strains value is converted in to stress value. Residual stress is quantified with respect to yield strength, making it possible to be considered for safe designing of weld components.
