| Abstract: | Method of formed camber of ship hull is introduced, approximate formulae of leastcontraction of length and area after doughnet-shaped surface formed are given , correctedcoefficient of unsymmetric camber and contraction of any longitudinal line are obtained. Twoexamples of real ship plates are presented. Comparison between measured data and computedresults shows that the precision satisfies engineering need. |
