A polynomial stress-strain relation is proposed for rotating disks with non-linear strain hardening materials. The basic equation of the disks with constant thickness and constant density under plane stress is derived from the deformation theory of plasticity, Von Mises’ yield criterion and the proposed stress-strain relation. A computing method for such rotating solid disks is developed and the approximate analytical solution is obtained. The validity of the solution is demonstrated by comparing the analytical calculation results with the finite element ones and very good agreement is found. The proposed solution is much more efficient and eassier to use than the FE approach
