Effect of Random Pinning on the Yielding Transition of Amorphous Solid under Oscillatory Shear
Roni Chatterjee, Monoj Adhikari, Smarajit Karmakar
We investigate the effects of random pinning, where we freeze the relaxation degrees of freedom for a fraction of randomly selected particles, on the yielding transition under osci…
Role of Fragility of the Glass Formers in the Yielding Transition under Oscillatory Shear
Roni Chatterjee, Monoj Adhikari, Smarajit Karmakar
Amorphous materials, especially metallic glasses, are known for their exceptional mechanical properties, such as high yield strength and large yield strain. Understanding the micro…
Encoding Robust and Fast Memories in Bulk and Nanoscale Amorphous Solids
Monoj Adhikari, Rishabh Sharma, Smarajit Karmakar
We investigate the memory effects under oscillatory shear deformation of amorphous solids through computer simulations. Applications of shear deformations in all orthogonal directi…
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…
Different glassy characteristics are related to either caging or dynamical heterogeneity
Puneet Pareek, Monoj Adhikari, Chandan Dasgupta +1
Despite the enormous theoretical and application interests, a fundamental understanding of the glassy dynamics remains elusive. The static properties of glassy and ordinary liquids…
Dependence of the glass transition and jamming densities on spatial dimension
Monoj Adhikari, Smarajit Karmakar, Srikanth Sastry
We investigate the dynamics of soft sphere liquids through computer simulations for spatial dimensions from to , over a wide range of temperatures and densities. Employin…
Yielding behavior of glasses under asymmetric cyclic deformation
Monoj Adhikari, Muhittin Mungan, Srikanth Sastry
We consider the yielding behaviour of a model glass subjected to asymmetric cyclic shear deformation, wherein the applied strain varies between 0 and a maximum value ,…
Spatial Dimensionality Dependence of Heterogeneity, Breakdown of the Stokes-Einstein Relation and Fragility of a Model Glass-Forming Liquid
Monoj Adhikari, Smarajit Karmakar, Srikanth Sastry
We investigate the heterogeneity of dynamics, the breakdown of the Stokes-Einstein relation and fragility in a model glass forming liquid, a binary mixture of soft spheres with a h…
Memory formation in cyclically deformed amorphous solids and sphere assemblies
Monoj Adhikari, Srikanth Sastry
We study a model amorphous solid that is subjected to repeated athermal cyclic shear deformation. It has previously been demonstrated that the memory of the amplitudes of shear def…
