Finite Disorder Critical Point in Brittle-to-Ductile Transition in Amorphous Solids with Aspherical Impurities
Anoop Mutneja, Bhanu Prasad Bhowmik, Smarajit Karmakar
Enhancing the mechanical properties of amorphous solids is crucial for material design, with microalloying being a common but not well-understood method. Using extensive molecular…
Length-scale Dependence of Stokes-Einstien Breakdown in Active Glass-forming Liquids
Anoop Mutneja, Smarajit Karmakar
Stokes-Einstein (SE) relation, which relates diffusion constant with the viscosity of a liquid at high temperatures in equilibrium, is violated in the supercooled temperature regim…
Athermal quasistatic cavitation in amorphous solids: effect of random pinning
Umang A. Dattani, Smarajit Karmakar, Pinaki Chaudhuri
Amorphous solids are known to fail catastrophically via fracture, wherein cavitation at nano-metric scales is known to play a significant role. Micro-alloying via inclusions is oft…
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…
Activity-Induced Annealing leads to Ductile-to-Brittle Transition in Amorphous Solids
Rishabh Sharma, Smarajit Karmakar
Investigating the behavior of amorphous solids under various external loading conditions continues to be an intriguing area of research with significant practical implications. In…
Cavitation instabilities in amorphous solids via secondary mechanical perturbations
Umang A. Dattani, Rishabh Sharma, Smarajit Karmakar +1
Amorphous solids are known to fail catastrophically and in some situations, nano-scaled cavities are believed to play a significant role in the failure. In a recent work, using num…
