| Abstract: | In view of the difficulty fixing material character and parameters, the modeling method for welding plate is presented. It combines mass and stiffness matrices from a finite element model with experimented mode shapes and natural frequencies to produce improved mass and stiffness matrices. The method enabled us to identify regions of original finite element models where the model parameters were incorrect. It is applied into from small sample problems and to large complex structures. |
