Abstract :
This paper presents two-dimensional stress and strain behavior of a FG
rotating cylindrical shell subjected to internal-external pressure, surface shear
stresses due to friction, an external torque, and constant temperature field.
A power law distribution was considered for thermomechanical material
properties. First order shear deformation theory (FSDT) was used to define
the displacement and deformation field. Energy method and Euler equation
were employed to derive constitutive differential equations of the rotating
shell. Systems of Six differential equations were achieved. Eigenvalue and
eigenvector methods were used to solve these equations. It was found that
the material grading index has a significant effect on stresses and strains
of a rotating functionally graded material cylindrical shell in radial and
longitudinal directions.
