Stability by homogenization of thermoviscoplastic problems
In this paper we study the homogenization of the system of partial differential equations describing the quasistatic shearing of heterogeneous thermoviscoplastic materials. We first prove the existence and uniqueness of the solution of the system for the general model. We then define “stable by homogenization” models as the models where the equations in both the heterogeneous problems and the h...
متن کاملShear band spacing in thermoviscoplastic materials
A closed-form expression for shear band spacing in strain-hardening, strain-rate-hardening and thermally softening thermoviscoplastic materials is derived by studying the stability of a homogeneous solution of equations governing its simple shearing deformations. The wavelength of the perturbation that maximizes its initial growth rate is assumed to determine the shear band spacing, Ls: The dep...
متن کاملHomogenization of ferromagnetic materials
In these notes we describe the homogenzation theory for ferromagnetic materials. A new phenomenon arises, in particular to take into account the geometric constraint that the magnetization is locally saturated.
متن کاملDynamic shear band development in dipolar thermoviscoplastic materials
354 Abstract We study thermomechanical deformations of a viscoplastic body deformed in plane strain compression at a nominal strain-rate of 5000 sec~. We develop a material model in which the second order gradients of the velocity field are also included as kinematic variables and propose constitutive relations for the corresponding higher order stresses. This introduces a material characterist...
متن کاملDependence of instability strain upon damage in thermoviscoplastic materials
BASED ON THE FIELD EQUATION for the number density of voids and the expression for the expansion of a spherical void in a perfectly plastic infinite body subjected to a uniform hydrostatic tensile stress, an expression for the rate of dilatation of voids is derived. Damage is defined as the volume density of voids. The flow stress of the material is assumed to decrease affinely with an increase...
