Abstract : Finite and infinitesimal deformation of an infinitely extended, axisymmetric disk of a non-uniform initial thickness with a circular hole is considered. The disk is loaded along the interior surface of the hole by pressure and twisting moment of non-decreasing magnitudes. A state of plane stress is assumed and the incremental theory of plasticity is used. Comparison is made between solutions for elastic-plastic and rigid-plastic disks. (Author)
