Gordo, J.M. and Teixeira, G. (2021), “A simplified method to simulate residual stresses in plates”, Developments in Maritime Technology and Engineering, Guedes Soares, C. & Santos T.A., (Eds.), Taylor and Francis, London, UK, Vol 1, pp. 785-792.
Welded structures are subjected to internal residual stress after manufacturing that may affect the structural strength and normally are associated with an increase on initial geometrical imperfections. This study presents a simplified method to generate an adequate representation of residual stresses on Finite Element models for structural analysis of thin-walled structures and other applications. The results obtained shown that the methodology proposed to introduce residual stresses is simple, accurate and efficient on the modulation of post-welding stresses and their pattern, thus it may be used for simulation of the thermal process.
