[28] concluded that if either monotonic or moving loads are considered, the results through the Timoshenko beam are almost the same as the Euler-Bernoulli beam. A detailed comparison of deflection of rail beams predicted by different theories subjected to varying train speeds can be found in [...
The problem of determining the parametric large deflection components of Euler–Bernoulli cantilever beams subjected to combined tip point loading is studied in this paper. We introduce the characteristic equation of the beam's deflection and, with employing the recently developed automatic Taylor expansio...

The current beam theories are the Euler-Bernoulli beam theory and the Rayleigh-Timoshenko beam theory. 现有的梁理论主要有Euler-Bernoulli和Rayleigh-Timoshenko梁理论,本文从现有的Timoshenko梁理论入手,先后介绍了几种计算Timoshenko梁动力响应的理论方法:模态叠加法、传递矩阵法和回传射线矩阵法,并应用几种方法分...
A sequence of elastic Reddy-type shear deformable beams of increasing (odd) order is envisioned, which starts with the Euler–Bernoulli beam (first order) and terminates with the Timoshenko beam (infinite order). The kinematics of the generic beam, including the warping mode of the cross section...
