Abstract This paper presents a novel computer‐aided computational framework to determine the optimum shape parameters in welding heat source model using coupled supervised Gaussian process regression (GPR) and genetic algorithm (GA) approach estimating residual stresses. The experimental X‐ray diffraction (XRD) validates optimization‐improved thermal–mechanical simulation method. validation of proposed includes welded plates with simple geometry pipe‐to‐plate circular hollow section joints...
This article presents an enhanced particle swarm optimization (EPSO) algorithm for size and shape of truss structures. The proposed EPSO introduces a categorization mechanism into the (PSO) to eliminate unnecessary structural analyses during process improve computational efficiency PSO-based optimization. numerical investigation, including three benchmark problems, examines EPSO. results demonstrate that greatly reduces requirements approaches while maintaining original search capability...
This paper introduces a novel digital twin solution for unlocking the elasto-plastic fatigue crack growth within an S550 steel under negative load ratios. The transforms solely strain data from strain-interfaced welded plate joint specimen to load–displacement curve compute cyclic J-integral values using η approach, eliminating need and displacement measurements. accurate computation of ΔJ effectively extends relationship derived standard fracture specimens. extended accurately predicts life...
