Rate dependent shear bands in a shear transformation zone model of amorphous solids
M. L. Manning, E. G. Daub, J. S. Langer +1
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 fo…
Anomalous diffusion in heterogeneous glass-forming liquids: Temperature-dependent behavior
J. S. Langer
In a preceding paper, Mukhopadhyay and I studied the diffusive motion of a tagged molecule in a heterogeneous glass-forming liquid at temperatures just above a glass transition. Am…
Strain localization in a shear transformation zone model for amorphous solids
M. L. Manning, J. S. Langer, J. M. Carlson
We model a sheared disordered solid using the theory of Shear Transformation Zones (STZs). In this mean-field continuum model the density of zones is governed by an effective tempe…
Dynamics and Thermodynamics of the Glass Transition
J. S. Langer
The principal theme of this paper is that anomalously slow, super-Arrhenius relaxations in glassy materials may be activated processes involving chains of molecular displacements.…
Thermal Effects in the Shear-Transformation-Zone Theory of Amorphous Plasticity: Comparisons to Metallic Glass Data
M. L. Falk, J. S. Langer, L. Pechenik
We extend our earlier shear-transformation-zone (STZ) theory of amorphous plasticity to include the effects of thermally assisted molecular rearrangements. This version of our theo…
Dynamics of Shear-Transformation Zones in Amorphous Plasticity: Energetic Constraints in a Minimal Theory
J. S. Langer, L. Pechenik
We use energetic considerations to deduce the form of a previously uncertain coupling term in the shear-transformation-zone (STZ) theory of plastic deformation in amorphous solids.…
