and buckling of Timoshenko beams possessing homogeneous and nonhomogeneous
properties and complex cross-section. The proposed exact solution is derived from 3D
elasticity equations. The Hamilton's integral equation is initially employed to establish the 3D
exact governing Partial Differential Equations (PDEs) of motion and buckling, taking into
account the effect of biaxial load applied to Timoshenko beams possessing complex cross …
