A new finite element formulation of three-dimensional beam theory based on interpolation of curvatureZupan, Dejan (Avtor) Saje, Miran (Avtor) 3D beamrotationscurvaturefinite element methodA new finite element formulation of the *kinematically exact finite-strain beam theory* is presented. The finite element formulation employs the generalized virtual work in which the main role is played by the pseudo-curvature vector. The solution of the governing equations is found by using a combined Galerkin-collocation algorithmTechno Press20032015-07-10 10:12:38Neznano32162UDK: 624.072:519.63ISSN pri članku: 1526-1492COBISS_ID: 1931617OceCobissID: 1931361sl
