Abstract
The problem of optimal design with respect to ductile creep rupture time for rotating disks is solved. The finite strain theory is applied, the material is described by the Norton-Bailey law generalized for true stresses and logarithmic strains. The set of four partial differential equations describing the problem is derived. The optimal shape of the disk is found using parametric optimization with one or two free parameters. The results are compared with disks of uniform thickness.
