Dynamics of shear-transformation zones in amorphous plasticity: non-linear theory at low temperatures

摘要

We use considerations of energy balance and dissipation to derive aself-consistent version of the shear-transformation-zone (STZ) theory ofplastic deformation in amorphous solids. The theory is generalized to includearbitrary spatial orientations of STZs. Continuum equations for elasto-plasticmaterial and their energy balance properties are discussed.
