Özet:

 

A computational model is developed to predict partially  plastic stresses in variable thickness annular disks subject to radial  compression.  The model is based on the von Mises' yield criterion,  deformation theory of plasticity and a Swift type hardening law.   Considering a thickness profile in the form of a general parabolic  function, the condition of occurrence of plastic deformation at the  inner and outer edges of the annular disk is investigated.  A critical  disk profile is determined and the corresponding elastic-plastic  stress as well as the residual stress distribution is computed.
