Regularized formulations of strain-softening plasticity
2003This chapter provides a simple introduction into continuum-based modeling of localized inelastic processes such as cracking or formation of shear bands. The main focus is on softening plasticity models regularized by higher-gradient terms or by weighted averaging of internal variables.

Plastic-strain-softening waves in crystals
Physics of the Solid State, 2001A system of equations describing the process of plastic deformation in a crystal is used to investigate self-sustained traveling structures theoretically. The equations for the velocity and density of dislocations are shown to describe two types of instability which are associated with anomalous damping of dislocations and structural disordering ...

Strain Space Approach for Softening Plasticity
Journal of Engineering Mechanics, 1987A formulation of the theory of plasticity in the strain space, which is a special case of the theory developed by Naghdi and coworkers, is presented here. A method to develop hardening functions to treat softening materials is discussed and illustrated.
