In the contribution, our 3D FGM Timoshenko beam finite element with 12x12 stiffness and mass matrices for doubly symmetric open and closed cross-section [1] is extended by warping torsion effect (non-uniform torsion) to 14x14 finite element matrices.

The application of first order shear beam theory in the analysis of beam structures made of functionally graded materials requires the access to homogenized stiffness quantities. These quantities depend on the cross-sectional shape and on the spatial

Torsional properties of prismatic shafts are typically analyzed by assuming rigid in-plane rotations of the cross-section accompanied with appropriate out of plane warping deformations. The most frequently applied strategy in that field is Vlasov’s

In this paper, the influence of longitudinal variation of material properties on the deformation and stresses of thin-walled non-uniformly twisted Functionally Graded Material (FGM) beams is investigated. The longitudinal variation is described by a

Mechanical properties of slender, prismatic structures are typically analyzed based on classical beam mechanics (Timoshenko’s shear force bending, Vlasov’s theory of warping torsion, …). There it is assumed that the cross-section remains rigid
