The purpose of this study is to design the initial shape of doubly curved hull surfaces. In this paper, the development method of the hull surfaces was suggested by minimizing potential energy between initial and final shapes. In order to do this, the values of strains and stresses were defined through finite element analysis and genetic algorithm was used to estimate the initial shape which is the state of minimum potential energy. Validity of the prediction method was verified by comparing the estimated contour lengths with those obtained by the commercial software for sheet metal forming. It was founded that the established prediction method using genetic algorithms would enable to determine the initial contour of the doubly curved surfaces with maximum deviation of 0.7%.
