The technique of finite elements has brought about a new era to the field of structural analysis of ship structures. The application of this technique, however, is limited by the cost and capacity of the computer. Straight forward applications of the finite element method to the whole or to a major portion of the ship have so far been inaccurate and too expensive for design purposes. The method presented combines the advantages of the finite element technique and the uncoupling by coordinate transformation. A fine mesh may now be used to produce more accurate boundary conditions. The uncoupling transformations also reduce the computer time to about one-tenth of that by other methods. The critical assumptions and the basic theories have been verified with experimental test results from the tanker John A. McCone. Three FORTRAN 4 computer programs are described. They have been written for the UNIVAC 1108 and CDC 6600 computers. Author
