Reliable analysis of transverse vibrations of Timoshenko-Mindlin beams with respect to uncertain shear correction factor. (English) Zbl 0971.74041
Summary: We investigate the dependence of minimal eigenfrequencies on the shear correction factor for homogeneous prismatic beams with simply supported or clamped ends. It is proved that the eigenfrequency is simple, and its derivative with respect to the shear correction factor is positive.
