Webb27 maj 2024 · Abstract. To solve integrals in the absolute nodal coordinate method and address the difficulty in applying it to an arbitrary-section beam, this paper focuses on two methods involving single integrals:the invariant matrix method and the Gerstmayr method, with cross-section characteristics by applying the interpolation of a discrete function. WebbTimoshenko beam theory is applied to discribe the behaviour of short beams when the cross-sectional dimensions of the beam are not small compared to its length. Here in this project, we develop the theoretical formulation for three-dimentional Timoshenko beam element undergoing axial, torsional and bending deformations. Then we implement it
