%0 Journal Article %T A SHEAR LOCKING-FREE BEAM FINITE ELEMENT BASED ON THE MODIFIED TIMOSHENKO BEAM THEORY %A Cho %A Dae Seung %A Senjanovi£¿ %A Ivo %A Vladimir %A Nikola %J - %D 2013 %X Sa£¿etak An outline of the Timoshenko beam theory is presented. Two differential equations of motion in terms of deflection and cross-section rotation are comprised in one equation and analytical expressions for displacements and sectional forces are given. Two different displacement fields are recognized, i.e. flexural and axial shear, and a modified beam theory with extension is worked out. Flexural and axial shear locking-free beam finite elements are developed. Reliability of the finite elements is demonstrated with numerical examples for a simply supported, clamped and free beam by comparing the obtained results with analytical solutions %K Timoshenko beam theory %K modified beam theory %K flexural vibrations %K axial shear vibrations %K beam finite element %K shear locking %U https://hrcak.srce.hr/index.php?show=clanak&id_clanak_jezik=171774
