Abstract
Results of the elastoplastic analysis of a rotating solid cylinder with fixed ends under monotonic loading by centrifugal forces are reported. The problem formulation is based on the theory of infinitesimal elastoplastic strains. The unified piecewise-linear yield condition and the associated flow law are used for calculating the plastic component of the strain. The adopted plasticity condition depends on a parameter that can be considered as a material characteristic. An exact solution of the governing system of equations is derived. Regular features of plastic flow development are found. It is demonstrated that six plastic domains are formed in the cylinder in the general case; these domains correspond to different edges and faces of the surface defined by the unified piecewise-linear condition. A dependence of the plastic limit velocity of cylinder rotation on the parameter included into the yield condition is derived.
