This chapter presents the analytical description of thick, or so-called shear-flexible, beam members according to the Timoshenko theory. Based on the three basic equations of continuum mechanics, i.e., the kinematics relationship, the constitutive law, and the equilibrium equation, the partial ...
Timoshenko beam theory has been intensively studied from the point of view of the mode approach. The focus of the present paper is distinct from other review articles on Timoshenko beam theory in that it reviews the wave solutions predicted by Timoshenko beam theory, their physical meanings and ...
Euler beam theory is always used for soil–pile analysis; however, its use is questionable for laterally loaded large-diameter monopiles. In this paper, th... G Cao,SC Chian,ZP Zhou - 《International Journal of Geomechanics》 被引量: 0发表: 2023年 Applicability of Timoshenko, Euler-Bernoull...
Based on the porous media theory and Timoshenko beam theory, properties of dynamic responses in fluid-solid coupled incompressible saturated poroelastic Timoshenko beam are investigated by generalized multi-symplectic method. Dynamic response equation se
