Timoshenko beam equations

WebIn this paper, the dynamic response of a simply supported beam subjected to a moving load is reinvestigated. Based on a new beam theory, slope inertia-based Timoshenko (SIBT), the governing equations of motion of the beam are derived. An analytical solution is presented by using a coupled Fourier and Laplace–Carson integral transformation method. … The Timoshenko–Ehrenfest beam theory was developed by Stephen Timoshenko and Paul Ehrenfest early in the 20th century. The model takes into account shear deformation and rotational bending effects, making it suitable for describing the behaviour of thick beams, sandwich composite beams, or beams … See more In static Timoshenko beam theory without axial effects, the displacements of the beam are assumed to be given by where $${\displaystyle (x,y,z)}$$ are the coordinates of a … See more In Timoshenko beam theory without axial effects, the displacements of the beam are assumed to be given by where $${\displaystyle (x,y,z)}$$ are the coordinates of a point in the beam, Starting from the … See more Determining the shear coefficient is not straightforward (nor are the determined values widely accepted, i.e. there's more than one answer); generally it must satisfy: See more • Plate theory • Sandwich theory See more
