AN analysis of creep deformations in rotating disks of constant and variable thicknesses by experimental and theoretical methods, has been presented by Wahl and his collaborators in a series of papers. Wahl first based his theory on the Mises Criterion and found that it gave creep deformations which were too low compared to the test-values. Later he carried out his investigations using, in the first instance, Maximum Shear Theory with the flow rule associated with Mises Criterion and in the second, the Tresca Criterion with its associated flow rule, assuming zero radial-creep-strain rate. He has concluded that better agreement between the test and theoretical values could be obtained in the later cases.
