Stress Analysis of Variable Thickness FGM Rotating Disks by Element based Material Gradation under Thermomechanical Loading
Abstract: The present research work aims to analyze deformation and stresses, induced in functionally graded rotating disks of variable thicknesses. The disks are made of exponential functionally graded material, whose mechanical and physical properties vary in radial direction. Functionally gradation of the properties is achieved by element-based gradation. Uniform as well as variable thickness, namely concave profile, convex profile and linear varying profile rotating disks are analyzed for clamped-free and free-free …

A Finite Element Solution of Functionally Graded Rotating Disk based on Element based Material Grading
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 …
