Authors: Vega, Adán; Plazaola, Carlos; Banfield, Ilka; Rashed, Sherif; Murakawa, Hidekazu

Description: The Elastic Finite Element Method based on the inherent strain theory is used to predict the welding distortion of ship structures. In addition, a method to predict welding distortion of complex structures by using elastic FEM is presented. To evaluate the effectiveness of the proposed method, a typical case of a ship's structure is examined and the resulting welding distortion is compared to that obtained by using thermal elastic-plastic finite element method.
