Cascade at local yield strain for silica and metallic glass
Nandlal Pingua, Himani Rautela, Roni Chatterjee +3
We report observations of unusal \emph{first} plastic events in silica and metallic glasses in the shear startup regime at applied strain two orders of magnitude smaller than yield…
Yielding in amorphous solids reveals an age-dependent intrinsic lengthscale
Aparna Sreekumari, Monoj Adhikari, Nandlal Pingua +5
Understanding how amorphous solids yield under shear is central to predicting material failure, yet prescribing reliable local yielding criteria remains a fundamental challenge. He…
Dynamical instability causes the demise of a supercooled tetrahedral liquid
Arvind Kumar Gautam, Nandlal Pingua, Aashish Goyal +1
We investigate the relaxation mechanism of a supercooled tetrahedral liquid at its limit of stability using isothermal isobaric () Monte Carlo (MC) simulations. In similarity…
The freezing tendency towards 4-coordinated amorphous network causes increase in heat capacity of supercooled Stillinger-Weber silicon
Pankaj A. Apte, Nandlal Pingua, Arvind Kumar Gautam +4
The supercooled liquid silicon, modeled by Stillinger-Weber potential, shows anomalous increase in heat capacity , with a maximum value close to 1060 K at zero pressure.…
