The present work reports the static behaviour of functionally graded rotating beam based on Timoshenko theory, which includes effect shear deformation. principle virtual displacement is applied to derive a governing equation for (FG) beam, considering centrifugal stiffening effect. B-spline collocation technique employed solve differential and material properties are function power law distribu...

Over the past decades, numerous damage diagnosis techniques based on modal flexibility have been studied and developed for various types of structures, but rarely structures made functionally graded (FG) materials. This paper aims to present extensive applicability a sensitivity-based index termed as MFBDI identification FG beams. The formulation this is closed-form sensitivity derived from dir...

In this work, a finite element model to perform the thermal–structural analysis of beams made functionally graded material (FGM) is presented. The formulation based on third-order shear deformation theory. constituents FGM are considered vary only in thickness direction, and effective properties evaluated by means rule mixtures. volume distribution top constituent modeled using power law form. ...

Buckling of a simply supported three-layer circular cylindrical shell under axial compressive load is studied. The inner and outer layers of the shell are comprised of the same homogeneous and isotropic material, and the middle layer is made of an isotropic functionally graded (FG) material whose Young’s modulus varies either affinely or parabolically in the thickness direction from its value f...
