Abstract:
For the purpose of carrying out the large deformation finite element analysis of spatial curved beams, the total Lagrangian(TL)and the updated Lagrangian(UL)incremental formulations for arbitrary spatial curved beam elements are established with displacement vector interpolation, which is improved from component interpolation of the straight beam displacement. A strategy of replacing the actual curve with the isoparametric curve is used to expand the applications of the UL formulation. The examples indicate that the process of establishing the curved beam element is correct, and the accuracy with the curved beam element is obviously higher than that with the straight beam element. Generally, the same level of computational accuracy can be achieved with 1/5 as many curved beam elements as otherwise with straight beam elements.
