Abstract

The present study reports the stress and deformation analysis of thick rotating disks made of two-dimensional functionally graded materials (FGMs). The analysis is carried out using element based gradation of material properties in radial and axial direction over the discretized domain. Material properties are distributed according to power law distribution and the governing equations are derived using principle of stationary total potential (PSTP). The resulting deformation and stresses are evaluated for clamped-free boundary condition and the effect of volume fraction exponent on the deformation and stresses is investigated and presented. The results obtained show that there is a significant reduction of stresses in two-dimensional FGM disks as compared to homogeneous and one-dimensional FGM disks. Further, it is observed that FGM having volume fraction exponents nr=2 and nz=1 is best suitable for the rotating thick disk as it has the low radial stress and deformation.
