Three-dimensional thermomechanical analysis of circumferentially welded thin-walled pipes

Residual stress simulation in thin and thick-walled stainless steel pipe welds including pipe diameter effects

“…Welded structures are an essential part of many buildings, bridges, ships, pipes, pressure vessels, nuclear reactors and other engineering structures [1,2]. Circumferentially welded pipes are often used in oil transport systems and steam piping for conventional and nuclear systems.…”

“…In their brief review of weld simulation, Teng and Chang [1] state that a thermomechanical model was developed by Friedman [4] using the FE method to calculate temperatures, stresses and distortions during welding; that elastoplastic FE computer programs were developed by Muraki [5] to monitor welding thermal stresses and metal movement; that residual stresses were estimated by Josefson [6] in a multi-pass weld and in a spot-welded box beam with SOLVIA and ABAQUS, which are commercially available FE codes for non-linear analyses; and that temperatures and stresses were analysed by Karlsson [7] and Karlsson and Josefson [8] in single-pass girth butt welding of carbon-manganese pipe using the FE codes ADINAT and ADINA.…”

Numerical solutions of transient temperature and thermally induced stress distributions in a solid disk heated with radially periodic expanding and contracting ring heat flux

“…Recently, the thermally induced stress analyzes with the heat transfer for several geometries and boundary conditions have been solved numerically by many researches [1][2][3][4][5][6][7][8]. Teng and Chang [1] have studied thermomechanical analysis of circumferentially welded thin-walled pipes, which are frequently used in boiling water reactor piping systems, oil pipe transport systems and steam piping systems.…”

Prediction of residual stresses and distortions due to laser beam welding of butt joints in pressure vessels

“…Moreover, validated numerical simulation tools for the analysis and optimization of the entire pressure vessel and pipework welding process, e.g. [16], are very important as regards the decrease of welding time (i.e. highspeed LBW) and increase of product quality (i.e.…”
