Cyclic plasticity phenomena as predicted by polycrystal plasticity

Mechanics of Materials, 2000
Abstract The elasto-viscoplastic Taylor–Lin model of polycrystal plasticity is employed to simulate the cyclic behavior of polycrystalline metals. Uniaxial tension–compression as well as biaxial cyclic deformations are examined by imposing the strain amplitude. Microscopic hardening law is used to account for the self and latent hardening of the slip

Cyclic plasticity and substructure of metals

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2002
Fatigue of metals is a consequence of cyclic plastic deformation. Fatigue properties, as well as the mechanical properties in general, are strongly dependent on the starting substructure. Moreover, the substructure undergoes changes during cyclic loading.

Plastic Internal Variables Formalism of Cyclic Plasticity

Journal of Applied Mechanics, 1976
The notion of Plastic Internal Variables (PIV) is used in reformulating, in a general form, the equations of rate-independent plasticity. The stress, temperature, and the PIV are the state variables for the present development. Loading-unloading is defined in terms of the usual loading function of classical plasticity.

Cyclic plasticity of trusses

Archive of Applied Mechanics, 2014
In this paper, the Preisach model of hysteresis, which was already successfully implemented for solving problems of cyclic plasticity of axially loaded bar and cyclic bending of elastoplastic beam, is extended to the structural analysis of trusses subjected to cyclic loading.
