RISOn a Finite Element Formulation of Dynamical Torsion of Beams Including Warping Inertia and Shear Deformation Due to Nonuniform Warping
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We start from the energetical expressions of dynamical torsion of beams in terms of angular and warping displacement and velocity. We derive the stiffness and two mass matrices including both ...
Limitation of Simplified Hypotheses for the Prediction of Torsional Oscillations for Thin-Walled Beams
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The study of uniform torsion of thin walled beams is done fairly easily in the thin wall beam case, the effects of thickness being neglected. Then, the classical Saint-Venant warping function ...
