| Abstract: | Based on the large deflection incremental theory in solid mechanics, the finite strip method in structural analysis was extended and an elasto plastic large deflection spline finite strip method established, based on the Updated Lagrangian method. A C language software package FSMAP (Finite Strip Method Analysis Program) was developed in this paper, and was used to analyze the thin plate. It was proved that the results agree well with those given in literatures. The method has the advantage of being stable in calculation and flexible in the treatment of boundary conditions. |
