Structural heterogeneity of amorphous solids present difficult challenges that stymie the prediction of plastic events, which are intimately connected to their mechanical behavior. Based on a perturbation analysis of the potential energy landscape, we derive the atomic nonaffinity as an indicator with intrinsic orientation, which quantifies the contribution of an individual atom to the total nonaffine modulus of the system. We find that the atomic nonaffinity can efficiently characterize the…

Insights from the quantitative calibration of an elasto-plastic model from a Lennard-Jones atomic glass
We compare the macroscopic and the local plastic behavior of a model amorphous solid based on two radically different numerical descriptions. On the one hand, we simulate glass samples by atomistic

A rotationally non-invariant local structure representation is introduced that enables different predictions for different loading orientations, which is found essential for high-fidelity prediction of the propensity for stress-driven shear transformations.
Predicting plasticity in disordered solids from structural indicators
Amorphous solids lack long-range order. Therefore identifying structural defects --- akin to dislocations in crystalline solids --- that carry plastic flow in these systems remains a daunting
Evaluating the predictive power of machine learning model for shear transformation in metallic glasses using metrics for an imbalanced dataset
This study trains a graph neural network that predicts the initially activated STZ and evaluates its predictive power using various metrics considered to be proper for handling imbalanced datasets, finding that the AUC value is significantly overestimated due to the class imbalance and too many atoms are misclassified as initial STZ.
Ergodic Structural Diversity Predicts Dynamics in Amorphous Materials
Identification of flexible local environments from a disordered medium has been a long-standing challenge. Here, we introduce a time-relevant structural Shannon entropy as a unique feature of the
Predicting plastic events and quantifying the local yield surface in 3D model glasses
Simple and Broadly Applicable Definition of Shear Transformation Zones.
The proposed definition of plasticity carriers in amorphous solids is more broadly applicable compared to anharmonic definitions put forward previously and is offered as an open-source library that analyzes low-lying STZs in computer glasses and in laboratory materials for which the harmonic approximation is accessible.


Statistical physics of the yielding transition in amorphous solids.
It is shown that the statistics of the energy barriers ΔE that need to be surmounted changes from a probability distribution function that goes smoothly to zero as ΔE=0 to a pdf which is finite at ΔE =0 .
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 , where the
Dynamics of viscoplastic deformation in amorphous solids
We propose a dynamical theory of low-temperature shear deformation in amorphous solids. Our analysis is based on molecular-dynamics simulations of a two-dimensional, two-component noncrystalline
Local thermal energy as a structural indicator in glasses
This work proposes that fluctuational thermal energy reveals highly localized and soft structures in glasses, and shows that the degree of softness of these “soft spots” follows a universal fat-tailed statistical distribution and relate it to the density of noncrystalline vibrational states.
Anisotropic structural predictor in glassy materials.
A structural predictor is constructed as the product of the local heat capacity and its linear response to external deformation, and it is shown that it offers an enhanced predictability of plastic rearrangements under deformation in different directions, compared to the purely scalar predictor.
Universal structural parameter to quantitatively predict metallic glass properties
‘flexibility volume’ is introduced as a universal indicator, to bridge the structural state the MG is in with its properties, on both atomic and macroscopic levels, and demonstrates that flexibility volume is a physically appropriate parameter that can quantitatively predict the shear modulus.
Stochastic approach to plasticity and yield in amorphous solids.
The PDF's of both Δγ and λ are not continuous functions of γ, and the nature of these transitions and scaling relations with the system size dependence of 〈Δγ〉 are discussed.
Local yield stress statistics in model amorphous solids.
It is argued that plastic rearrangements are the consequence of shear transformation zones encoded in the glass structure that possess weak slip planes along different orientations, justifying the hypothesis of an average characteristic amplitude often conjectured in mesoscopic or continuum models.
Soft spots and their structural signature in a metallic glass
A structure–property correlation in metallic glasses for the community of amorphous solids associates geometrically unfavored motifs, i.e., those most disordered local polyhedral packing structures in a metallic glass, with the soft spots defined from the vibrational modes and correlates them with shear transformation zones composed of atoms with large nonaffine displacements.
Connecting Local Yield Stresses with Plastic Activity in Amorphous Solids.
The sites of low local yield stress are shown to be persistent, remaining predictive of deformation events even after fifty or more such plastic rearrangements, reinforcing the relevance of modeling plasticity in amorphous solids based on a gradually evolving population of discrete and local zones preexisting in the structure.
