Stresses and Deformation in Rotating Disk During Over-Speed
Abstract Disks of rotating machineries like gas turbine engines of aircraft are subjected to very high centrifugal stresses during extreme maneuvering conditions. These disks operate in nonlinear plastic region and may grow plastically during over-speed/over-load resulting in permanent deformation. As per certification criterion, disks should have acceptable permanent growth after over-speed. A closed-form solution is developed to predict permanent residual growth in rotating disk with variable thickness for linearly strain hardening material behavior using Tresca’s yield criteria and its associated flow rule. Results obtained using analytical solutions have been compared with finite element method (FEM) and experimental tests results for uniform thickness disks
