Rate-dependent shear bands in a shear-transformation-zone model of amorphous solids.
We use shear transformation zone (STZ) theory to develop a deformation map for amorphous solids as a function of the imposed shear rate and initial material preparation. The STZ formulation incorporates recent simulation results [T. K. Haxton and A. J. Liu, Phys. Rev. Lett. 99, 195701 (2007)] showing that the steady state effective temperature is rate dependent. The resulting model predicts a w...
متن کاملSurface shear-transformation zones in amorphous solids.
We perform a systematic study of the characteristics of shear transformation zones (STZs) that nucleate at free surfaces of two-dimensional amorphous solids subject to tensile loading using two different atomistic simulation methods, the standard athermal, quasistatic (AQ) approach and our recently developed self-learning metabasin escape (SLME) method, to account for the finite temperature and...
متن کاملOn the density of shear transformations in amorphous solids
We study the stability of amorphous solids, focussing on the distribution P (x) of the local stress increase x that would lead to an instability. We argue that this distribution behaves as P (x) ∼ x, where the exponent θ is larger than zero if the elastic interaction between rearranging regions is non-monotonic, and increases with the interaction range. For a class of finite-dimensional models ...
متن کاملMicrostructural shear localization in plastic deformation of amorphous solids.
The shear-transformation-zone (STZ) theory of plastic deformation predicts that sufficiently soft, noncrystalline solids are linearly unstable against forming periodic arrays of microstructural shear bands. A limited nonlinear analysis indicates that this instability may be the mechanism responsible for strain softening in both constant-stress and constant-strain-rate experiments. The analysis ...
متن کاملMicroscopic mechanism of shear bands in amorphous solids.
The fundamental instability responsible for the shear localization which results in shear bands in amorphous solids remains unknown despite an enormous amount of research, both experimental and theoretical. As this is the main mechanism for the failure of metallic glasses, understanding the instability is invaluable in finding how to stabilize such materials against the tendency to shear locali...
