Optimization‐improved thermal–mechanical simulation of welding residual stresses in welded connections

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 9, Page 1275-1293, 1 May 2024.
Abstract This paper presents a novel computer‐aided computational framework to determine the optimum shape parameters in a welding heat source model using a coupled supervised Gaussian process regression (GPR) and genetic algorithm (GA) approach in estimating the welding residual stresses. The experimental X‐ray diffraction (XRD) approach validates the
