The inelastic behavior of solid circular bars twisted to arbitrarily large strains is considered. Various phenomenological constitutive laws currently employed to model finite strain inelastic behavior are shown to lead to closed-form analytical solutions for torsion. These include rate-independent elastic-plastic isotropic hardening J2 flow theory of plasticity, various kinematic hardening models of flow theory, and both hypoelastic and hyperelastic formulations of J2 deformation theory. Certain rate-dependent inelastic laws, including creep and strain-rate sensitivity models, also permit the development of closed-form solutions. The derivation of these solutions is presented as well as numerous applications to a wide variety of time-independent and rate-dependent plastic constitutive laws.

Stress Cycling

The application of recovery creep theory to the prediction of cyclic loading and heating response of a specific high temperature alloy is illustrated for four different cyclic shapes. It is shown that a satisfactory approximation to the quasi-steady state cyclic response of the material after a number of loading cycles can be obtained from a single computation by comparison with the results of cycle-by-cycle integration. The special form of recovery creep theory employed assumes isotropic hardening and therefore does not predict a symmetrical creep strain response under symmetrical stress cycling.
