Chen, B.Q. and Guedes Soares, C. (2018), “A simplified model for the effect of weld induced residual stresses on the axial ultimate strength of stiffened plates”, Journal of Marine Science and Application, Vol. 17, pp. 57-67

The present work investigates the compressive axial ultimate strength of fillet-welded steel-plated ship structures subjected to uniaxial compression, in which the residual stresses in the welded plates are calculated by a thermo-elastoplastic finite element analysis that is used to fit an idealised model of residual stress distribution. The numerical results of ultimate strength based on the simplified model of residual stress show good agreement with those of various methods including the International Association of Classification Societies (IACS) Common Structural Rules (CSR), leading to the conclusion that the simplified model can be effectively used to represent the distribution of residual stresses in steel-plated structures in a wide range of engineering applications. It is concluded that the widths of the tension zones in the welded plates have a quasi-linear behaviour with respect to the plate slenderness. The effect of residual stress on the axial strength of the stiffened plate is analysed and discussed.
