| Abstract: | Curved beam finite element model with muhinomial as displacement has error because of membrane force locking and shear force locking. The validation of self-organizing program and one largescale commercial software proves that the cell rigidity matrix and consistent mass matrix of curved beam displacement satisfying border constraint condition have excellent accuracy, and it servers as the reference for practical engineering. |
