The Absolute Node Coordinates Method of Large Deformation of the Flexible Beam System
Jing Guo, Chunhua Zhao

Abstract
The application of an absolute nodal coordinate formulation (ANCF) in the coupling dynamics of flexible beams with large deformation was investigated. By using geometric nonlinear formulation and finite element method, the dynamics equations of planar beams system were developed by using the ANCF. The comparison between the ANC formulation and nonlinear strain-displacement formulation in the case of small deformation and large deformation indicates that the ANC formulation is more precise and suited for the beams with large deformation. The present results are verified by using the energy conservation law.
