摘要: Abstract A computational model is developed to investigate inelastic deformations of variable thickness rotating annular disks mounted on rigid shafts. The von Mises yield condition and its flow rule are combined with Swift’s hardening law simulate nonlinear material behavior. An efficient numerical solution procedure designed used throughout handle the nonlinearities associated boundary at shaft–annular disk interface. results computations verified by comparison an analytical employing Tresca’s criterion available in literature. Inelastic stresses calculated for described two different commonly profile functions i.e. power exponential forms. Plastic limit angular velocities these values geometric parameters. These critical found increase as edge reduces. Lower plastic obtained made nonlinearly materials.
