In the analysis of the stress and deformation under dynamic loading, the inertia force and damping moment should be considered in addition to the transverse shear effect.
在分析动载荷下的应力和变形时，除考虑横向剪切效应外，还须考虑微段的惯性力和阻尼力矩。

From numerical example, the effect of shear deformation and rotatory inertia on the natural frequencies of the Timoshenko clamped beam is discussed under different slender conditions.
通过算例，计算了在不同长细比条件下，剪切变形和转动惯量对固端梁的各阶主频率的影响。

It is also shown that the influence of the rotary inertia of the mass block on the shear failure is not negligible.
