Journal ArticleDOI
Numerical simulation of temperature field and residual stress in multi-pass welds in stainless steel pipe and comparison with experimental measurements
Dean Deng,Hidekazu Murakawa +1 more
TL;DR: Based on the ABAQUS software, uncoupled thermal-mechanical three-dimensional and two-dimensional (2-D) finite element models are developed in this article to evaluate the transient temperature and the residual stress fields during welding.
Journal ArticleDOI
Prediction of welding distortion and residual stress in a thin plate butt-welded joint
Dean Deng,Hidekazu Murakawa +1 more
TL;DR: In this paper, a three-dimensional, thermo-elastic-plastic, large deformation finite element method (FEM) is used to simulate welding distortion in a low carbon steel butt-welded joint with 1mm thickness.
Journal ArticleDOI
Numerical simulation of welding distortion in large structures
Journal ArticleDOI
Prediction of welding residual stress in multi-pass butt-welded modified 9Cr–1Mo steel pipe considering phase transformation effects
Dean Deng,Hidekazu Murakawa +1 more
TL;DR: In this article, a thermal elastic plastic finite element model taking into account the metallurgical phase transformation was developed to investigate the influence of solid-state phase transformation on the evolution of residual stress distributions in butt-welded modified 9Cr-1Mo steel pipes.
Journal ArticleDOI
Determination of welding deformation in fillet-welded joint by means of numerical simulation and comparison with experimental measurements
TL;DR: In this article, a 3-D thermal elastic plastic finite element computational procedure is developed to precisely predict welding deformation by numerical method, and the simulated results are in a good agreement with the experimental measurements.
