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…
Memory behavior of a randomly driven model glass
Roni Chatterjee, Smarajit Karmakar, Muhittin Mungan +1
We investigate by atomistic simulations the memory behavior a model glass subjected to random driving protocols. The training consists of a random walk of forward and/or backward s…
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…
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…
