Abstract

The present study reports finite element elastic analysis of variable thickness rotating disks made up of functionally graded materials (FGMs). The disks have exponentially varying material properties along the radius, which is achieved by varying the volume fraction ratio. Three types of thickness profile namely uniform, linearly varying and concave thickness profile having constant mass are analyzed and the resulting displacement and stresses areevaluated for free-free boundary condition. The investigation is carried out using element based grading of material properties on the discretized elements. A comparison of displacement and stresses for uniform thickness disk and variable thickness disk is madewhich shows that in a rotating disk, the displacement and stress fields can be controlled by varying the thickness of the disk. Cite this ArticleAmit Kumar Thawait, LakshmanSondhi.
