چکیده

We study the shear-induced fluidization of amorphous solids subjected to external loading by investigating relaxation dynamics deformed states using computer simulation. A simple shear deformation is employed at constant rate thermal glassy materials. The localization and plastic heterogeneity with strain investigated in terms non-affine displacement field. mean square shows an enhanced mobility particles strain, indicating material. Using time correlation function we estimate sheared glasses. significant decrease observed up yielding point as material loses its solid nature eventually becomes liquid-like. Finally, imprint memory quiescent sample on rheological properties melted glass computing stress. find a finite persistent residual stress that outlasts experimental observation our system.

Surface 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...

Emergent interparticle interactions in thermal amorphous solids.

Amorphous media at finite temperatures, be them liquids, colloids, or glasses, are made of interacting particles that move chaotically due to thermal energy, continuously colliding and scattering off each other. When the average configuration in these systems relaxes only at long times, one can introduce effective interactions that keep the mean positions in mechanical equilibrium. We introduce...

On 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 ...

Microstructural 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 ...

Microscopic 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...
