Thereafter, the established elastic finite element model is extended to nonlinear analysis. In the aspect of geometrical nonlinearity, from the incremental virtual work equation described in the referential configuration at the moment of T=0 and T=t, geometrical stiffness matrices in TL formulation and UL formulation are deduced respectively. In the aspect of material nonlinearity, assume that the material is perfect plastic, complying with Von-Mises's yielding rule and related flowing rule. With the finite segment method, one of distributed plasticity models, where certain Guassian points are collocated along the element length and the natural coordinate of cross section, the element elasto-plastic stiffness matrix is derived by Guassian quadrature. In every incremantal step, constitutive integration is performed by the generalized midpoint method. Also, on the basis of the geometrically nonlinear model and material nonlinear model, a spatial thin-walled beam element with doubly nonlinear behavior is produced.
