Size distribution of emitted energies in local load sharing fiber bundles

Subhadeep Roy, Soumyajyoti Biswas

We study the local load sharing fiber bundle model and its energy burst statistics. While it is known that the avalanche size distribution of the model is exponential, we numerical…

Crack Localization and the Interplay between Stress Enhancement and Thermal Noise

Santanu Sinha, Subhadeep Roy, Alex Hansen

We study the competition between thermal fluctuations and stress enhancement in the failure process of a disordered system by using a local load sharing fiber bundle model. The the…

Phase transitions and correlations in fracture processes where disorder and stress compete

Santanu Sinha, Subhadeep Roy, Alex Hansen

We study the effect of the competition between disorder and stress enhancement in fracture processes using the local load sharing fiber bundle model, a model that hovers on the bor…

Creep failure in a threshold activated dynamics: Role of temperature during a sub-critical loading

Subhadeep Roy, Takahiro Hatano

Creep is a time-dependent deformation of solids at relatively low stresses, leading to the breakdown with time. Here we propose a simple model for creep failure of disordered solid…

Fiber bundle model under heterogeneous loading

Subhadeep Roy, Sanchari Goswami

The present work deals with the behavior of fiber bundle model under heterogeneous loading condition. The model is explored both in the mean-field limit as well as with local stres…

Modes of failures in disordered solids

Subhadeep Roy, Soumyajyoti Biswas, Purusattam Ray

The two principal ingredients determining the failure modes of disordered solids are the level of heterogeneity and the length scale of the region affected in the solid following a…
