摘要：Efficient isogeometric curved beam element is formulated to investigate the free vibration behavior of spatial beam structures with arbitrary curvature and torsion. Beam structures are described by multi patch non-uniform rational B-splines. Isogeometric formulation with Timoshenko beam theory is applied with global formulation. Compared with prior formulations that use local formulation within a single patch, the present global formulation of stiffness and mass matrices for multi patch structures is effective in dealing with complex structures. Numerical tests are carried out on a series of models including a conceptual framework of an automobile to show the effectiveness of the present method. (C) 2017 Elsevier Masson SAS.
