Abstract : Critical conditions for shear localization in thermoviscoplastic materials are obtained in closed form for idealized models of simple shearing deformations. The idealizations, which include the neglect of heat conduction, inertia, and elasticity, are viewed as quite acceptable for many applications in which shear bands occur. Explicit results obtained for the idealized, but fully nonlinear problem show the roles of strain rate sensitivity, strain hardening, and initial imperfection… 
Approximate Analysis of a Shear Band in a Thermoviscoplastic Material
Shear localization is systematically examined with the aid of an approximate modelfor the three stages of deformation in the formation and development of shear band, which comprise: the growth of
The role of rate effects and of thermomechanical coupling in shear localization
A dislocation density related constitutive model that accounts for the strain-rate sensitivity of the flow stress and, notably, of the strain-hardening coefficient was applied to describe adiabatic
Biaxial Loading of Continuously Graded Thermoviscoplastic Materials
In this paper we study the problem of biaxial loading of a sheet made of a continuously graded thermoviscoplastic material. The material phases are supposed to exhibit thermal softening, strain-rate


Analysis of Shear Strain Localization in Thermal Visco-Plastic Materials.
Abstract : Simple shearing deformations are analyzed as a means of investigating the effects of strain hardening, thermal softening, and strain-rate sensitivity on the formation of shear bands.
