On the Steady-State Creep of Rotating Solid Disks

Abstract

Here is described an analytical method on the steady-state creep of a rotating disk with variable thickness and nonuniform temperature distribution. The numerical computation by this method is easy. Creep tests of rotating solid disks of forged 18-8 Mo stainless steel were carried out in a hot spin tester prepared by the author and his associates. At the same time, specimens were cut out from the various parts of the disks and put to creep tests and other material tests. The analytical results were compared with experimental ones. Mises criterion has shown better agreement with the test data.
