Stress analysis of axisymmetric rotating disk of uniform thickness with various shapes

Rotating disks are vital parts of every moving machine. Thus, improving the stress bearing ability and stress distribution of such disks will benefit every industry. Most researches about rotating disks have been carried out considering variable thickness, functionally graded materials, and other specific conditions regarding the applications in the industry. In this study, rotating disks of various geometries of uniform thickness are considered with simple material configuration. The rotating disks are modeled in SolidWorks 2013 and analyzed using ANSYS Workbench 16.0 software. Stresses on different loading conditions are observed and compared, also the effect on stress distribution for different fillet radius is observed and compared with the aim to increase overall stress bearing ability. The study reveals that stress bearing ability of such disks is improved with fillet radius. Study also reveals that loading applied near the rotational axis results in greater stress bearing ability usually. However, this varies greatly with the geometry and the shape of the rotating disk.
