Stress and displacement analysis of a rotating FGM annular disk

In this study, a rotating annular disk with angular velocity w under constant temperature, having a constant thickness and material properties which vary along the radial coordinate is considered. The effects of the material properties on the distribution of the stress, strain components and radial displacement are investigated. In this study, elasticity modulus, density and linear coefficient of thermal conductivity of the disk?s material are assumed as functions of the radial coordinate 1 0 E = E r b , 2 0 b r = r r , 3 0 b a =a r respectively. After compatibility equation, equation of motion, deformation and radial displacement are stated in dimensionless form. Effect of b varies on stress, strain and radial displacement are also investigated. Key Words : Functionally Graded Materials , Rotating Disks
