• Resumen

  • The Drucker–Prager yield criterion is used in conjunction with its associated ow rule to nd the elastic/plastic stress and strain distributions within the rotating annular disks under plane stress conditions. The main distinguished feature of the model, as compared to typical models used for analysis of disks, is that the material is plastically compressible. Using an approach proposed elsewhere, the solution for strain rates is reduced to one nonlinear ordinary dierential equation and two linear ordinary dierential equations.

    These equations can be solved one by one, which signicantly simplies the numerical treatment and increases the accuracy of soluti
