Amorphous solids are critical in the design and production of nanoscale devices, but under strong confinement these materials exhibit changes in their mechanical properties which are not well understood. Phenomenological models explain these properties by postulating an underlying defect structure in these materials but do not detail the microscopic properties of these defects. Using machine learning methods, we identify mesoscale defects that lead to shear banding in model polymer nanopillars…

The initiation of shear band formation in deformed metallic glasses from soft localized domains.
It is observed that shear band formation indeed occurs through the strain-induced formation of localized soft regions in the authors' deformed metallic glass free-standing films, and the critical strain condition for SB formation occurs when the softness distribution within the emerging soft regions approaches that of the interfacial region in its undeformed state.
Predicting the location of shear band initiation in a metallic glass
We report atomistic simulation results which indicate that the location of shear banding in a metallic glass (MG) can be ascertained with reasonably high accuracy solely from the undeformed static
Effect of polymer-nanoparticle interaction on strain localization in polymer nanopillars.
This study used molecular dynamics simulations to investigate the influence of NPs on the tendency of a polymer nanopillar to form a shear band, and shows that weak interactions between NP and polymer matrix can form a soft region near the NP, and this leads to an attraction of theShear band to the NP surface.
Physical insights into stress–strain process of polymers under tensile deformation via machine learning
ABSTRACT Strain localization is a ubiquitous phenomenon of soft matters subjected to strain. Polymeric materials are a very important class of soft materials and widely used nowadays. Polymers have
Understanding Creep Suppression Mechanism in Polymer Nanocomposites through Machine Learning
While recent efforts have shown how local structure plays an essential role in the dynamic het-erogeneity of homogeneous glass-forming materials, systems containing interfaces such as thin films or
Confinement effects on the mechanical heterogeneity of polymer fiber glasses.
This work performs molecular dynamics simulations and shows that the nonaffine displacement during deformation relates closely to the mechanical response of the polymer fibers, and in the strain-hardening regime there is a significant difference in the energetic contribution to the stress between polymer fibers and bulk polymers.
Distinguishing failure modes in oligomeric polymer nanopillars.
This work uses molecular dynamics simulations to capture ductile-to-brittle transition in glass-forming oligomeric polymer systems where it is found that the transition between catastrophic brittle failure, necking, and homogeneous plastic flow is gradual as the temperature is increased.
Strain localization and failure of disordered particle rafts with tunable ductility during tensile deformation.
Quasi-static tensile experiments were performed for a model disordered solid, and local interactions between anisotropic sites and particle rearrangements were the main mechanisms driving strain localization and the subsequent failure, and significant differences of such interactions exist between ductile and brittle behaviors.
Structuro-elasto-plasticity (StEP) model for plasticity in disordered solids
Elastoplastic lattice models for the response of solids to deformation typically incorporate structure only implicitly via a local yield strain that is assigned to each site. However, the local yield
Deep Learning for Automated Classification and Characterization of Amorphous Materials
It is shown that convolutional neural networks and message passing neural networks can classify two-dimensional liquids and liquid-cooled glasses from molecular dynamics simulations with greater than 0.98 AUC, with no a priori assumptions about local particle relationships, even when the liquids and glasses are prepared at the same inherent structure energy.


Strain localization in glassy polymers under cylindrical confinement.
This work uses molecular dynamics simulations to investigate the mechanical response of model glassy polymers confined to a nanoscopic pillar under tensile deformation and finds that samples that are cooled at a slower rate and deformed at a faster rate are more prone to localization of the strain response, or shear banding.
Structure-property relationships from universal signatures of plasticity in disordered solids
A range of particle-based and glassy systems show universal features of the onset of plasticity and a universal yield strain, and a microscopic structural quantity, “softness,” designed by machine learning to be maximally predictive of rearrangements is links structure to plasticity in disordered solids.
Confinement Effect on Strain Localizations in Glassy Polymer Films
The physical properties of glassy polymer films change as they become confined. These changes are often attributed to increased average molecular mobility and reduction in entanglement density. Both
Strain localization in a shear transformation zone model for amorphous solids.
A criterion is derived that determines which materials exhibit shear bands based on the initial conditions alone, and it is shown that the shear band width is not set by an inherent diffusion length scale but instead by a dynamical scale that depends on the imposed strain rate.
Theory of Shear Banding in Metallic Glasses and Molecular Dynamics Calculations
The aged-rejuvenation-glue-liquid (ARGL) shear band model has been proposed for metallic glasses (Acta Mater. 54 (2006) 4293), based on small-scale molecular dynamics simulations up to 20,000 atoms
Using shape anisotropy to toughen disordered nanoparticle assemblies.
It is demonstrated that anisotropic nanoparticles greatly suppress shear band formation and toughen nanoparticle packings without sacrificing their strength, implying that tuning constituent anisotropy can be used to enhance toughness in disordered packings of nanoparticles.
Directly Measuring the Complete Stress–Strain Response of Ultrathin Polymer Films
The inherently fragile nature of ultrathin polymer films presents difficulties to the measurement of their mechanical properties, which are of interest in packaging, electronics, separations, and
Deformation-driven diffusion and plastic flow in amorphous granular pillars.
It is found that different-sized pillars follow self-similar shape evolution during deformation, and the yield stress of the pillars increases linearly with pillar size, indicating that in athermal granular packings, the cumulative deviatoric strain plays the role of time in thermal systems and drives effective particle diffusion.
Machine learning characterization of structural defects in amorphous packings of dimers and ellipses.
This work studies a model disordered solid, a bidisperse two-dimensional granular pillar, driven by uniaxial compression and composed entirely of monomers, dimers, or ellipses, and introduces structure functions to recover the predictive performance of softness and identifies the most crucial structure functions in determining softness.
