| Abstract: | The problems in computing beam\|shell\|composed structures with the finite element method are pointed out, and a corresponding solution method is proposed based on the finite deformation theory. Numerical examples show the validity and correctness of the present theory. Not only proper for the nonlinear computation of beam\|shell\|composed structures in large deformation problems, the proposed method is suitable for linear small deformation problems as well. |
