Abstract

In this paper, the inherent strain method is employed for the purpose of predicting welding residual stresses in large shell structures. Such structures include roof structures in the construction industry and deck sections in the shipbuilding industry. The study focuses on the numerical aspect of the inherent strain method, with the objective of investigating the most appropriate technique for transferring analytically calculated inherent strains into the elastic finite element model of the structure. The approach under consideration takes into account the thermally induced stresses, to the extent that they are considered to be significant for the structures and their behaviour in question, with the objective of determining the field of welding residual stresses over the entire structure (macro-scaled). The work proposes theoretical parameters for the alignment of finite element meshes within the weld seam domain. The discussion in the conclusion encompasses the general application capabilities, limitations, and challenges for further development
