Phenomenological evolution equations for the backstress and spin tensors

Acta Mechanica, 1991
This paper is concerned with a formulation of a constitutive model involving a new kinematic hardening rule. The corotational stress and backstress rate involvig spin tensors are discussed and incorporated in the evolution equations. The backstress model is compared with other models and is found to be decomposable into a model that consists of two ...

A microphysical model of rock friction and the brittle-ductile transition controlled by dislocation glide and backstress evolution

Journal of Geophysical Research: Solid Earth, 2022
AbstractRate‐ and state‐friction (RSF) is an empirical framework that describes the complex velocity‐, time‐, and slip‐dependent phenomena observed during frictional sliding of rocks and gouge in the laboratory. Despite its widespread use in earthquake nucleation and recurrence models, our understanding of RSF, particularly its time‐ and/or slip ...

Experimental and numerical investigation of texture evolution and the effects of intragranular backstresses in aluminum alloys subjected to large strain cyclic deformation

International Journal of Plasticity, 2017
Abstract Strain hardening in FCC metals and alloys can be accompanied by the formation of deformation induced dislocation microstructures. These microstructures tend to form dislocation cells or nets which are characterized by three-dimensional tangles of dislocations that serve as “cell walls” and less dense internal regions “cell interiors”.
