A consistent finite element model for a circular wheel is developed based on triangular and quasi-triangular elements and a piecewise-linear displacement field. The minimum stress-rate principles of plasticity are used to obtain solutions of two-dimensional continuum problems with internal unloading. A piecewise-linear approximation of the Tresca yield condition is used. Elastic-plastic solution of a wheel with a hub load rolling on a rigid track is obtained for the first few revolutions until a steady-state condition is reached. A shakedown condition for the wheel is demonstrated.
