【Abstract】 Based on the principle of the matrix displacement method, the program for computing the stability of the grillage in the large sized carrier is compiled. This thesis also shows the subroutines for the auto division of the finite elements, one dimension array storage of the large scale matrix and calculation of critical stress by negative power method. Finally some examples are given to show the effectiveness of the program.更多还原
