Abstract
In this paper two modifications for the finite rotation formulation and for the rotation update procedure are proposed, both avoid the singularity of the rotation matrix and improve the convergence of non-linear finite elemen t computations considerably. Compared with the reference results, the effec tiveness of these modifications is demonstrated by numerical examples, (C) 2001 Civil-Comp Ltd. and Elsevier Science Ltd. All rights reserved.
