Stiffness matrix of thin-walled curved beam for spatially coupled stability analysis
International Journal of Mechanical Sciences, 2008Abstract The exact stiffness matrix for the spatially coupled stability analysis of thin-walled curved beam with non-symmetric cross-section subjected to uniform compression is newly presented. For this, the elastic strain energy including the axially/flexurally/torsionally coupled terms and the potential energy due to the initial stress resultant ...

Coupled vibrations of beams—an exact dynamic element stiffness matrix
International Journal for Numerical Methods in Engineering, 1983AbstractA uniform linearly elastic beam element with non‐coinciding centres of geometry, shear and mass is studied under stationary harmonic end excitation. The Euler‐Bernoulli‐Saint Venant theory is applied. Thus the effect of warping is not taken into account.

Exact dynamic stiffness matrix of a bending-torsion coupled beam including warping
Computers & Structures, 1996Abstract It is known that an allowance for warping stiffness can change the natural frequencies of thin-walled open section beams substantially. The purpose of this paper is to investigate the magnitude of such changes by using an exact member theory.

An exact dynamic stiffness matrix for coupled extensional-torsional vibration of structural members
Computers & Structures, 1994Summary: Exact analytical expressions for coupled extensional-torsional dynamic stiffness matrix elements of a uniform structural member are derived from the basic governing differential equation of the member in free vibration. Application of the derived dynamic stiffness matrix is discussed with particular reference to an established algorithm.

Tangent Stiffness Matrix of Spatial Beam Element Considering Bend and Torsion Coupling Effect
Advanced Materials Research, 2014Based on the spatial beam-column differential equations, the slope deflection equations considering second-order and bend-torsion coupling effect are established. The additional moment caused by torsion and bend deflection are taken into account. Then the finite element pattern of spatial beam-column considering the couple effect of torsion and bend is
