Abstract: In the present article, a semi-analytical technique to investigate free bending vibration behavior of axially functionally graded non-prismatic Timoshenko beam subjected to a point force at both ends is developed based on the power series expansions. The beam is assumed to be made of linear elastic and isotropic material with constant Poisson ratio. Material properties including the ...

For the first time, structural dynamics and vibrational stability of a viscoelastic axially functionally graded (AFG) beam with both spinning axial motions subjected to an load are analyzed, aim enhance performance bi-gyroscopic systems. A detailed parametric study is also performed emphasize influence various key factors such as material distribution type, viscosity coefficient, coupled rotati...

in this paper, a general solution for torsion of hollow cylinders made of functionally graded materials (fgm) was investigated. the problem was formulated in terms of prandtl’s stress and, in general, the shear stress and angle of twist were derived. variations in the material properties such as young’s modulus and poisson’s ratio might be arbitrary functions of the radial coordinate. various m...
