Modes of failure in disordered solids

S Roy, S Biswas, P Ray - Physical Review E, 2017 - APS
The two principal ingredients determining the failure modes of disordered solids are the
strength of heterogeneity and the length scale of the region affected in the solid following a …

Critical scaling through Gini index

S Das, S Biswas - Physical Review Letters, 2023 - APS
In the systems showing critical behavior, various response functions have a singularity at the
critical point. Therefore, as the driving field is tuned toward its critical value, the response …

Prediction of imminent failure using supervised learning in a fiber bundle model
