Description: Timoshenko beams in Abaqus/Standard now support linearly tapered general beam sections and standard library sections. A new improved mass formulation for linear Timoshenko beams is also available. The new mass matrix is based on cubic interpolations and provides much better estimates of the frequency response in models where the mesh is too coarse, especially when used in conjunction with the automatic calculation of the slenderness correction factor based on the section's elastic properties.
